Title
Pingvin Share X before 1.22.0 Rate Limit Bypass via Spoofed X-Forwarded-For
Summary
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.
Severity
6.5 (Medium)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
