CVE-2025-69413

Gitea's Tattletale API: User Enumeration via Error Messages

Jan 2, 2026·6 min read·67 visits

Executive Summary (TL;DR)

Gitea versions prior to 1.25.2 respond differently to login attempts depending on whether the username exists or not. Attackers can use this 'oracle' to build a list of valid users, paving the way for targeted credential stuffing or social engineering attacks.

A classic response discrepancy vulnerability in Gitea's API authentication logic allows unauthenticated attackers to enumerate valid usernames based on specific error messages.

CVE-2025-6965: Remote Code Execution via Integer Truncation in SQLite Aggregate Parser

An integer truncation vulnerability (CWE-197) exists in SQLite before version 3.50.2 during the processing of aggregate queries with more than 32,767 distinct column references. This causes an internal 32-bit counter to truncate to a signed 16-bit integer, producing negative values that cause out-of-bounds heap operations in release builds.

CVE-2026-11822: Memory Corruption and Buffer Overflow in SQLite FTS5 Extension

A memory corruption vulnerability exists in the FTS5 (Full-Text Search 5) extension of SQLite prior to version 3.53.2. An attacker can construct a malicious database file containing corrupt FTS5 page data. Querying this database triggers out-of-bounds reads and heap-based buffer overflows, potentially causing a crash or arbitrary code execution.

CVE-2026-56350: SSO Enforcement Bypass in n8n via API Parameter Pollution / Mass Assignment

A mass assignment vulnerability (CWE-915) in n8n's self-service settings API endpoint (PATCH /me/settings) allows authenticated Single Sign-On (SSO) users to disable SSO enforcement for their accounts by injecting administrative parameters. This bypasses organizational identity provider controls and multi-factor authentication (MFA).

CVE-2026-55699: Arbitrary Directory Deletion via Path Traversal in pnpm globalBinDir Resolver

CVE-2026-55699 (also identified as GHSA-4gxm-v5v7-fqc4) is a critical path traversal and arbitrary directory deletion vulnerability in the pnpm package manager. The issue exists because the manifest validation process fails to prevent relative path segments within the package 'bin' keys. When a malicious package containing structured path traversal markers is globally installed and later manipulated, pnpm resolves the target paths through path.join() and passes the resolved paths to a recursive deletion function, resulting in arbitrary directory removal.
