What is CVE-2026-91829?

The Subscribe to Comments WordPress plugin prior to version 2.3.3 is vulnerable to reflected cross-site scripting due to inadequate parameter validation. This flaw allows an unauthenticated attacker to craft a malicious URL that, when clicked by a user, including administrators, can lead to the execution of arbitrary scripts in the context of the victim's browser. Consequently, this may enable the attacker to steal sensitive information, manipulate user sessions, or perform other nefarious actions.

Affected Version(s)

Subscribe to Comments 0 < 2.3.3

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
