CVE-2025-30949Network attack vector

Unauthenticated object injection via untrusted deserialization

Published Jul 16, 2025 · Updated Apr 28, 2026

PHP object injection in Guru Team Site Chat on Telegram 1.0.4 and earlier allows remote attackers to inject objects via untrusted input. Published sources do not identify the input field or function that passes attacker-controlled serialized data into PHP deserialization. Exploitation is unauthenticated, but damaging effects require a suitable POP chain from another installed plugin or theme; the resulting action depends on that chain.
