CWE-284 27/05/2026
pam_usb: deny_remote feature incorrectly classifies IPv4-mapped IPv6 remote connections as local
pam_usb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.0, pam_usb's deny_remote feature checks utmpx ut_addr_v6 to detect whether an authentication request originates from a remote session. The outer guard was if (utent->ut_addr_v6[0] != 0), which only tests the first 32-bit word of the 128-bit address field. IPv4-mapped IPv6 addresses (::ffff:x.x.x.x) store the IPv4 address in ut_addr_v6[3] with ut_addr_v6[0] == 0. On systems where the SSH daemon listens on :: (IPv6 wildcard) with AddressFamily any -- common on Ubuntu and Debian -- incoming IPv4 connections are recorded in utmpx as IPv4-mapped IPv6 addresses. The outer check evaluates to false, the remote-detection block is skipped entirely, and the session is treated as local. deny_remote=true does not block the authentication. An attacker with physical access to a registered USB device can authenticate over SSH on an affected system as if they were sitting at a local terminal, bypassing the deny_remote restriction. This vulnerability is fixed in 0.9.0.

CWE-284 27/05/2026
Samba: missing access check on reparse point operations
A flaw was found in Samba’s handling of NTFS-style reparse points on shares configured with read only = yes. Due to missing SMB-layer access checks, authenticated users with underlying filesystem write permissions may create or delete reparse point metadata through SMB operations even on read-only exports. This could allow modification of SMB-visible file behavior, including converting files into symbolic links or other reparse point types.

Compromised VM can make arbitrary blobstore deletes
AgentClient#handle_method (lines 264-303) processes every NATS reply. It calls inject_compile_log (line 273) on every response, which reads response['value']['result']['compile_log_id'] (line 332-338) and passes it to download_and_delete_blob. Separately, any response containing 'exception' goes through format_exception (lines 308-325), which reads exception['blobstore_id'] and also calls download_and_delete_blob. That helper (lines 344-349) calls ResourceManager#get_resource(blob_id) and, in an ensure block, ResourceManager#delete_resource(blob_id). ResourceManager (resource_manager.rb:62-70) calls blobstore.delete(id) on the single shared Director blobstore with no UUID-format check, no ownership check, and no namespace prefix.

e107: Broken Access Control in e107 comment edit allows cross-user comment modification
e107 is a content management system (CMS). Prior to 2.3.4, a Broken Access Control vulnerability exists in the application, allowing an unauthorized authenticated user to edit comments posted by others. This stems from inadequate server-side access control validation, where the application depends only on a predictable identifier in the request to determine which comment to edit, without confirming the requesting user’s ownership of the comment. This vulnerability is fixed in 2.3.4.

Versions of the package @koa/router from 14.0.0 and before 15.0.0 are vulnerable to Access Control Bypass due to the middleware being silently dropped from the execution chain when the router prefix contains path parameters. Depending on what the skipped middleware was supposed to protect, an attacker could bypass authentication and authorization, evade rate limiting or bypass input sanitization.

TypeBot: Cross-Workspace Credential Theft via Bot-Engine Preview Endpoint
TypeBot is a chatbot builder tool. In versions 3.15.2 and prior, the fix for GHSA-4xc5-wfwc-jw47 ("Credential Theft via Client-Side Script Execution and API Authorization Bypass") is incomplete. While the builder's getCredentials tRPC endpoint was patched with workspace membership checks, the bot-engine runtime still allows any authenticated user to use credentials from any workspace via the preview chat endpoint. The bot-engine's getCredentials() utility function uses a falsy check (if (workspaceId && ...)) for workspace ownership validation. Since the preview endpoint accepts a client-controlled workspaceId field and the Zod schema allows empty strings, an attacker can supply workspaceId: "" to bypass credential ownership verification entirely. Exploitation can result in credential exfiltration, external service abuse, financial damage and a data breach.
