Microsoft.OpenApi.YamlReader vulnerable to denial of service via YAML alias expansion
The OpenAPI.NET SDK contains a useful object model for OpenAPI documents in .NET along with common serializers to extract raw OpenAPI JSON and YAML documents from the model. In Microsoft.OpenApi.Readers versions before 1.6.30 and Microsoft.OpenApi.YamlReader from 2.0.0-preview.11 through 2.11.0 and 3.0.0 through 3.9.0, parsing a YAML OpenAPI document with nested anchors and aliases can consume uncontrolled memory. SharpYaml represents aliases as shared nodes in a small directed acyclic graph, but conversion to independent OpenAPI or System.Text.Json.Nodes.JsonNode trees duplicates every aliased path; without a node-count or nesting-depth limit, N nested anchors referenced k times can require k^N materialized nodes and terminate the process through an out-of-memory condition. The fixed readers bound materialization to 5,000,000 nodes and a nesting depth of 64 by default and report an OpenApiDiagnostic error when a limit is exceeded. This vulnerability is fixed in Microsoft.OpenApi.Readers 1.6.30 and Microsoft.OpenApi.YamlReader 2.12.0 and 3.10.0.
CVE-2026-47762 Medium · 5.4 CWE-79 May 28, 2026
TinyMCE Cross-Site Scripting (XSS) vulnerability through `mce:protected` comments
TinyMCE is an open source rich text editor. Prior to 5.11.1, 7.9.3, and 8.5.1, there is a stored XSS vulnerability via forged mce:protected comments. Allows attackers to bypass sanitization and inject scripts that execute when content is restored. Impacts users who utilize the protect option. This vulnerability is fixed in 5.11.1, 7.9.3, and 8.5.1.
CVE-2026-47761 Medium · 5.4 CWE-79 May 28, 2026
TinyMCE Cross-Site Scripting (XSS) vulnerability using media plugin `data-mce-object` injection
TinyMCE is an open source rich text editor. Prior to 5.11.1, 7.9.3, and 8.5.1, there is a stored XSS vulnerability in the media plugin. Attackers can inject malicious scripts via crafted data-mce-* attributes, which are executed when content is rendered. Impacts users of TinyMCE with the media plugin enabled. This vulnerability is fixed in 5.11.1, 7.9.3, and 8.5.1.
CVE-2026-47760 Medium · 5.4 CWE-79 May 28, 2026
TinyMCE Cross-Site Scripting (XSS) vulnerability using sanitization bypass through nested SVGs
TinyMCE is an open source rich text editor. From 6.8.0 to before 7.1.0, TinyMCE contains an XSS vulnerability caused by improper SVG namespace scope handling in the sanitizer. A crafted payload using nested elements can bypass attribute sanitization and execute arbitrary JavaScript. This vulnerability is fixed in 7.1.0.
CVE-2026-47759 Medium · 5.4 CWE-79 May 28, 2026
TinyMCE Cross-Site Scripting (XSS) vulnerability using through data-mce- prefixed src, href, style attributes
TinyMCE is an open source rich text editor. Prior to 5.11.1, 7.9.3, and 8.5.1, there is a stored XSS vulnerability via unsanitized data-mce-* attributes (data-mce-href, data-mce-src, data-mce-style). Allows attackers to inject malicious values that override safe attributes during serialization, bypassing validation. This vulnerability is fixed in 5.11.1, 7.9.3, and 8.5.1.
CVE-2026-39399 Critical · 9.6 CWE-20 Apr 14, 2026
NuGet Gallery: Arbitrary Blob Overwrite via Nuspec Confusion and URI Fragment Truncation
NuGet Gallery is a package repository that powers nuget.org. A security vulnerability exists in the NuGetGallery backend job’s handling of .nuspec files within NuGet packages. An attacker can supply a crafted nuspec file with malicious metadata, leading to cross package metadata injection that may result in remote code execution (RCE) and/or arbitrary blob writes due to insufficient input validation. The issue is exploitable via URI fragment injection using unsanitized package identifiers, allowing an attacker to control the resolved blob path. This enables writes to arbitrary blobs within the storage container, not limited to .nupkg files, resulting in potential tampering of existing content. This issue has been patched in commit 0e80f87628349207cdcaf55358491f8a6f1ca276.
CVE-2025-66625 Medium · 4.9 CWE-200 Dec 9, 2025
Umbraco Vulnerable to Improper File Access and Credential Exposure through Dictionary Import Functionality
Umbraco is an ASP.NET CMS. Due to unsafe handling and deletion of temporary files in versions 10.0.0 through 13.12.0, during the dictionary upload process an attacker with access to the backoffice can trigger predictable requests to temporary file paths. The application’s error responses (HTTP 500 when a file exists, 404 when it does not) allow the attacker to enumerate the existence of arbitrary files on the server’s filesystem. This vulnerability does not allow reading or writing file contents. In certain configurations, incomplete clean-up of temporary upload files may additionally expose the NTLM hash of the Windows account running the Umbraco application. This issue is fixed in version 13.12.1.
CVE-2025-64113 Critical · 9.8 CWE-640 Dec 9, 2025
Emby Server allows attackers to gain administrative server access without preconditions
Emby Server is a user-installable home media server. Versions below 4.9.1.81 allow an attacker to gain full administrative access to an Emby Server (for Emby Server administration, not at the OS level). Other than network access, no specific preconditions need to be fulfilled for a server to be vulnerable. This issue is fixed in version 4.9.1.81.
