AI Analysis
Technical Summary
This vulnerability (CVE-2026-39578) affects Elated-Themes Valiance software versions up to and including 1.2. It is caused by unsafe deserialization of untrusted data, allowing unauthenticated attackers with high privileges to perform PHP Object Injection. The CVSS 3.1 base score is 8.1, reflecting network attack vector, low attack complexity, required high privileges, no user interaction, and scope change with limited confidentiality and integrity impact. No vendor advisory or patch information is currently provided.
Potential Impact
Successful exploitation could allow an attacker with high privileges to inject malicious PHP objects, potentially leading to partial disclosure of sensitive information and unauthorized modification of data. There is no reported impact on system availability. The vulnerability affects confidentiality and integrity but not availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the affected software to trusted users only and monitor for unusual activity. Avoid processing untrusted serialized data if possible.
