CVE-2026-112852Deserialization of Untrusted Data vulnerability in ThemeREX Group Helion helion allows Object Injection.This issue affects Helion: from n/a through 1.1.12. Executive summary A deserialization flaw in the Helion WordPress theme from ThemeREX Group affects all versions through 1.1.12. Patchstack rates it high priority with a CVSS score of 8.1 and says it is expected to be exploited. The advisory says no official patch is available yet, and it recommends updating the theme once a fix exists, or asking a hosting provider or web developer for help if that is not possible. Technical summary The flaw is a PHP Object Injection caused by deserialization of untrusted data, which lets attackers manipulate how the site processes data to run harmful actions on the server. Patchstack lists the required privilege as unauthenticated, so no login is needed according to the advisory. The vulnerable versions are stated as from n/a through 1.1.12 and <= 1.1.12, and no patched version is stated because no official patch is available. Patchstack says it has issued a mitigation rule that blocks attacks until an official patch is applied, but the advisory does not describe that rule's details. The advisory does not state a specific workaround beyond updating, detection guidance, or whether exploitation has been observed in the wild. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
