CVE-2023-40600Network attack vector

Unauthenticated debug-data disclosure via predictable log filename

Published Nov 30, 2023 · Updated Apr 29, 2026

Sensitive information exposure in Exactly WWW EWWW Image Optimizer 7.2.0 and earlier allows remote attackers to read debug data. The plugin writes diagnostic output to a predictably named, web-accessible debug log instead of assigning the log an unpredictable filename. Exploitation requires debug logging to be enabled and exposes logged information without altering data or interrupting service.
