The vulnerability CVE-2025-64353 affects the Chouby Polylang plugin, allowing an attacker to perform deserialization of untrusted data resulting in object injection. This flaw exists in all versions up to 3.7.3. The CVSS 3.1 base score is 8.8, indicating a high impact with network attack vector, low attack complexity, requiring low privileges but no user interaction, and resulting in high confidentiality, integrity, and availability impacts. No patch or official remediation information is currently available.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code or manipulate application logic through object injection, leading to full compromise of the affected system's confidentiality, integrity, and availability. Given the high CVSS score, the impact is severe. However, there are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, it is recommended to restrict access to the vulnerable component and monitor for suspicious activity related to deserialization. Avoid processing untrusted data where possible.
