CVE-2026-108162 Details
Description
Pingvin Share X before 1.22.0 contains a rate limit bypass vulnerability that allows unauthenticated remote attackers to evade per-IP throttling because backend/src/main.ts unconditionally trusts proxy headers. Attackers can rotate spoofed X-Forwarded-For values against /api/auth/signIn, /api/auth/signIn/totp, and /api/auth/resetPassword to brute-force passwords and TOTP codes and forge logged client IP addresses.
A rate limit bypass vulnerability has been identified in Pingvin Share X versions prior to 1.22.0. This vulnerability allows unauthenticated remote attackers to evade per-IP throttling by exploiting the application's unconditional trust in proxy headers. Attackers can rotate spoofed X-Forwarded-For values to bypass rate limits on sensitive authentication endpoints, including password and TOTP code brute-forcing, as well as forging client IP addresses in audit logs.
Users are advised to update Pingvin Share X to version 1.22.0 or later, where this vulnerability has been patched. Instructions for updating can be found in the project's documentation.
