CVE-2023-45009Network attack vector

Unauthenticated CAPTCHA bypass via guessable challenges

Published Jun 4, 2024 · Updated Apr 28, 2026

CAPTCHA bypass in Forge12 Interactive GmbH SilentShield 1.11.3 and earlier allows remote attackers to submit forms without valid verification. Published records characterize the CAPTCHA as guessable but do not identify the generator, validator, or erroneous operation that makes challenge answers predictable. Exposure requires an enabled protected form, and the documented consequence is bypass of its anti-spam gate rather than broader WordPress authentication.
