By

2h ago· 4 min readenNews

Summary

A security researcher at Mythos Preview discovered a 29-year-old memory leak vulnerability in Squid, a widely-used open-source caching proxy server. Dubbed "Squidbleed" and reminiscent of the Heartbleed bug, the flaw silently leaked users' plaintext HTTP requests, potentially exposing sensitive data like credentials and session tokens since the Clinton era. The vulnerability was reported to project maintainers who fixed the code earlier this month. Squid is commonly deployed by large corporations, schools, and other organizations.
