CVE-2026-70554: Deserialization of Untrusted Data in MaxSite MaxSite CMSCVE-2026-70554
0

MaxSite CMS version 0.78 contains a critical PHP object injection vulnerability. This flaw allows unauthenticated attackers to execute arbitrary code by sending malicious serialized data in the maxsite_comuser cookie, which is unserialized without validation. The vulnerability enables exploitation via crafted payloads that trigger PHP magic methods during object reconstruction, potentially leading to remote code execution through gadget chains such as SoapClient or Imagick.
