CVE-2026-105695 Média · 5.9 CWE-862 05/10/2026

Penpot: Missing authorization in chunked-upload assembly lets another authenticated user consume a victim's upload session

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, assemble-chunks retrieves an upload session using only its session ID, while upload-chunk correctly scopes the lookup to the authenticated profile. An authenticated user who obtains another user's live, completed upload-session UUID can assemble the victim's chunks into the attacker's own file, team font, or project import, disclosing the uploaded bytes and deleting the victim's pending session. This issue is fixed in version 2.18.0.

CVE-2026-105696 Média · 6.5 CWE-862 05/10/2026

Penpot: Share-link page-scope escalation: a share-link holder reads pages outside the link's authorized scope via the get-page RPC command

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the get-page RPC accepts a share-link permission object with blanket read access but does not verify that the caller-selected page-id belongs to the link's authorized pages set. An attacker with both a valid share link and the attacker's own authenticated Penpot session can retrieve the complete shape and design data of another page in the same file when its identifier is known, because get-page requires authentication. The related get-file-fragment RPC also permits share-link access without mapping fragments to authorized pages. This issue is fixed in version 2.18.0.

CVE-2026-105694 Média · 5.4 CWE-79 05/10/2026

Penpot: Stored XSS via Unsanitised SVG Uploads

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, authenticated users with file-edit permission can upload SVG media whose scripts, event-handler attributes, and foreignObject elements are stored without sanitization and served as image/svg+xml from the Penpot origin. A victim who navigates to the asset URL executes attacker-controlled JavaScript in that origin, allowing requests and data access with the victim's Penpot session authority. This issue is fixed in version 2.18.0.

CVE-2026-105693 Média · 5.3 CWE-862 05/10/2026

Penpot: Anonymous share-link token disclosure & page-scope bypass via get-view-only-bundle

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the unauthenticated get-view-only-bundle RPC returns every share-link row for a file even when the caller authenticated with only one scoped share link. A holder of a restrictive link can obtain other links' secret IDs, page scopes, comment permissions, and inspection permissions, then replay a more permissive token to access page data that was not included in the original share. This issue is fixed in version 2.18.0.

CVE-2026-105692 Média · 5.4 CWE-284 05/10/2026

Penpot: IDOR in Share-Link Deletion Allows Any File Editor to Delete Share-Links They Did Not Create

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the delete-share-link RPC retrieves a caller-selected share-link ID and verifies only that the caller can edit the parent file. It does not verify that the caller created the share link or has owner or administrator authority, allowing any file editor who knows a share-link UUID to delete links created by other users and revoke external reviewers' access. This issue is fixed in version 2.18.0.

CVE-2026-105691 Crítica · 9.9 CWE-78 05/10/2026

Penpot: Authenticated OS Command Injection in Penpot SVG Exporter via Legacy fill-color

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the SVG exporter places an attacker-controlled text object's fill-color value into a ppmcolormask command string and executes that string through child_process.exec. A user who can edit a file can store shell metacharacters in the fill color and trigger SVG export, causing commands to execute with the exporter service's privileges. The same export can be triggered through a valid public share link to a malicious file. This vulnerability is fixed in 2.18.0.

CVE-2026-105690 Média · 5.9 CWE-613 05/10/2026

Penpot: Server-side session not invalidated on logout; stale auth-token cookie remains valid for full profile access

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, logout clears the browser's auth-token cookie without revoking the corresponding server-side session. A previously captured session token remains usable after the victim logs out and can continue to make authenticated requests with the victim's authority until natural expiration. This issue is fixed in version 2.18.0.

CVE-2026-105689 Média · 6.0 CWE-918 05/10/2026

Penpot: SSRF guard bypass via IPv6 transition addresses (NAT64/6to4/Teredo) in webhook delivery and media download

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, app.util.ssrf/blocked-address? relies on Java InetAddress predicates that do not classify NAT64, 6to4, or Teredo addresses and applies additional CIDR checks only to IPv4 values. Exploitation requires routing through a NAT64 gateway or an attacker-controlled DNS AAAA record; cloud environments with NAT64 gateways are directly exploitable. A user controlling a media import URL, or an administrator controlling a webhook URL, can then supply an IPv6 transition address that embeds a cloud-metadata, loopback, link-local, or private IPv4 target and bypasses the intended SSRF restrictions. Media import can disclose response bodies, while webhook delivery can expose response status as a network-probing side channel. This issue is fixed in version 2.18.0.

CVE-2026-105688 Média · 6.7 CWE-269 05/10/2026

Penpot: Team admin can escalate to owner via team invitation (missing owner-role guard on the invitation path)

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, create-team-invitations and the invitation acceptance path allow a non-owner team administrator to assign the owner role because invitation roles are persisted and applied without the role-ceiling check used by update-team-member-role. An administrator can invite another account as an owner, create multiple owners, and then use the new owner account to obtain owner-only control over the team. This issue is fixed in version 2.18.0.

CVE-2026-105684 Média · 4.3 CWE-200 05/10/2026

Penpot: Share-link page-scope escape — comment RPCs leak comment content, author identity, and all page-ids for pages outside the share scope

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the get-comment-threads, get-comment-thread, and get-comments RPC commands use check-comment-permissions! but do not apply the share link's pages restriction. A holder of a page-scoped share link can retrieve comment threads and full comment bodies from other pages in the same file, including commenter names, email addresses, photos, and page identifiers. The disclosed page identifiers can also be used with affected page-reading functionality to access unshared design content. This issue is fixed in version 2.18.0.

CVE-2026-105687 Média · 4.9 CWE-269 05/10/2026

Penpot: A team admin (non-owner) can remove the team owner via ::delete-team-member — missing owner-protection

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the delete-team-member RPC allows a team administrator to remove any member other than themselves but does not protect the team owner. A non-owner administrator can delete the owner's team-profile-rel membership and lock the owner out of the team and its projects, files, fonts, and media. This issue is fixed in version 2.18.0.

CVE-2026-105686 Média · 5.3 CWE-770 05/10/2026

Penpot: Repeated chunk index causes temporary-storage amplification

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the chunked media upload RPC validates that a chunk index is in range but neither rejects an already stored index nor replaces its previous object. An authenticated user can repeatedly upload the same valid index, causing each successful request to allocate another temporary object and increasing stored bytes beyond the upload session's declared logical size. Assembly detects the inconsistent chunk count only after allocation. This issue is fixed in version 2.18.0.

CVE-2026-100868 Média · 6.3 CWE-1327 27/09/2026

Penpot before 2.18.0 Unauthenticated WebSocket Access via MCP Bridge

Penpot before 2.18.0 binds the MCP server plugin WebSocket bridge to all network interfaces without authentication in single-user mode. Unauthenticated attackers on adjacent networks can connect to the WebSocket port to impersonate the Penpot browser plugin, intercept task payloads, and return forged results to the MCP client.

CVE-2026-45806 Alta · 7.7 CWE-918 15/07/2026

Penpot: Authenticated SSRF in remote image import via create-file-media-object-from-url

Penpot is an open-source design tool for design and code collaboration. Prior to 2.15.0, Penpot's remote image import passed the user-controlled url from frontend/src/app/main/data/workspace/media.cljs into the backend RPC method :create-file-media-object-from-url in backend/src/app/rpc/commands/media.clj, where media/download-image in backend/src/app/media.clj used the shared HTTP client without destination filtering, allowing an authenticated file editor to reach internal-only endpoints. This issue is fixed in version 2.15.0.

CVE-2026-45805 Alta · 8.8 CWE-749 15/07/2026

Penpot: MCP REPL server binds to 0.0.0.0 with unauthenticated /execute endpoint — RCE

Penpot is an open-source design tool for design and code collaboration. Prior to 2.15.0, Penpot MCP's mcp/packages/server/src/ReplServer.ts bound the ReplServer to 0.0.0.0:4403 and exposed an unauthenticated /execute endpoint that passed the code field to PluginBridge.executePluginTask(), allowing anyone on the network to execute JavaScript on the server. This issue is fixed in version 2.15.0.

CVE-2026-44986 Crítica · 9.9 CWE-287 15/07/2026

Penpot: Pre-authenticated account takeover via team-invitation token + prepare-register-profile

Penpot is an open-source design tool for design and code collaboration. Prior to 2.14.5, Penpot exposed teams_invitations.clj invitation tokens from create-team-invitations, embedded an existing profile id in auth.clj prepare-register-profile, and had auth.clj register-profile issue a session based on the invitation email match without password verification, allowing a registered user to take over any non-blocked profile. This issue is fixed in version 2.14.5.

CVE-2026-26202 Alta · 7.5 CWE-22 19/02/2026

Penpot has Arbitrary File Read via create-font-variant RPC endpoint

Penpot is an open-source design tool for design and code collaboration. Prior to version 2.13.2, an authenticated user can read arbitrary files from the server by supplying a local file path (e.g. `/etc/passwd`) as a font data chunk in the `create-font-variant` RPC endpoint, resulting in the file contents being stored and retrievable as a "font" asset. This is an arbitrary file read vulnerability. Any authenticated user with team edit permissions can read arbitrary files accessible to the Penpot backend process on the host filesystem. This can lead to exposure of sensitive system files, application secrets, database credentials, and private keys, potentially enabling further compromise of the server. In containerized deployments, the blast radius may be limited to the container filesystem, but environment variables, mounted secrets, and application configuration are still at risk. Version 2.13.2 contains a patch for the issue.
