———A vulnerability was determined in SeaCMS up to 13.6. Affected is the function parseIf of the file search.php of the component Template Engine. This manipulation of the argument searchtype causes code injection. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized.5h CVE-2026-77956—

———Improper Control of Generation of Code (Code Injection) vulnerability in ash-project ash_ai allows a remote, unauthenticated client to execute arbitrary Elixir code. AshAi.Actions.Prompt evaluates prompt content through EEx.eval_string/2. The documented prompt: fn input, context -> ... end form lets the prompt content be built from action arguments, so when a prompt action's text incorporates request data, that attacker-controlled text is compiled and run as an EEx template (Elixir source). Content such as <%= System.cmd(...) %> therefore executes on the server before any model request is made, requiring no authentication beyond reaching a prompt action. The fix stops evaluating function-supplied prompt content as EEx; only statically configured templates are evaluated. This issue affects ash_ai: from 0.1.0 before 1.0.0.5h CVE-2026-825544.3 MED
