What is CVE-2026-92809?

The PrestaShop psgdpr module versions up to 1.4.3 exhibit a vulnerability where the system fails to properly verify that GDPR consent log entries belong to the authenticated user. This flaw allows authenticated attackers to exploit the application by submitting arbitrary customer identifiers, resulting in the creation of fraudulent consent records for other users. This not only compromises the integrity of audit logs but also poses significant risks to data protection compliance and customer privacy.

Affected Version(s)

psgdpr 0 <= 1.4.3

Exploit Proof of Concept (PoC)
