CVE-2024-48033Network attack vector

Unauthenticated object injection via unsafe deserialization

Published Oct 11, 2024 · Updated May 12, 2026

PHP object injection in Baptiste Gourdin TalkBack 1.0 and earlier allows remote attackers to inject objects through network requests. Patchstack identifies untrusted deserialization in the talkback-secure-linkback-protocol plugin but does not disclose the affected function, input field, or serialization flow. The record establishes unauthenticated reachability without user interaction but does not publish the concrete post-injection consequence.
