CVE-2026-39550

Vulnerability

Elated-Themes Aperitif versions prior to 1.6.1 contain a Deserialization of Untrusted Data vulnerability that allows for Object Injection. This vulnerability is present in the theme's PHP code and affects versions from n/a through 1.6 [1].

Exploitation

An attacker can exploit this vulnerability by triggering the deserialization of untrusted data. If a suitable POP chain is present, this can lead to various malicious actions, including code injection, SQL injection, path traversal, and denial of service [1].

Impact

Successful exploitation of this vulnerability can allow a malicious actor to execute arbitrary code, perform SQL injection, conduct path traversal attacks, or cause a denial of service. The scope and privilege level of the compromise depend on the specific POP chain used by the attacker [1].

Mitigation

Update Elated-Themes Aperitif to version 1.6.1 or later to resolve this vulnerability. If an immediate update is not possible, consult your hosting provider or web developer for assistance. Patchstack has provided a mitigation rule to block attacks until a patched version is installed [1].
