Local PII disclosure via retained browser cache
Published Nov 26, 2025 · Updated Nov 28, 2025
Information disclosure in Overhang.IO Tutor 20.0.2 allows local users to read cached account PII after another user logs out. The account settings response lacks cache-control headers, and the client does not reject history navigation after logout, leaving rendered PII in the browser cache. Exploitation requires prior authenticated use on the same browser and subsequent local access; the demonstrated consequence is read-only disclosure of account details.
