Summary

Acceptance of invalid/self-signed TLS certificates in "Foxit PDF - PDF reader, editor, form, signature" before 5.4 for iOS allows a man-in-the-middle and/or physically proximate attacker to silently intercept login information (username/password), in addition to the static authentication token if the user is already logged in.

Exploit prediction

0.52% chance of exploitation in the next 30 days, higher than 44% of all scored CVEs (FIRST EPSS, 2026-11-09).

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
