CVE-2026-81891 is an unrestricted file upload vulnerability in Studio 42 elFinder, an open source web file manager embedded in a wide range of PHP applications and content management systems. The flaw sits in the checkExtractItems() function in php/elFinderVolumeDriver.class.php, which calls mimetypeInternalDetect() without passing the result through mimeTypeNormalize().

Zenity is built to implement those controls at runtime. Here's the 2026 OWASP Top 10 for LLM Applications, entry by entry, with the gaps marked honestly. Paste a booby-trapped instruction into a chat window, and nothing much happens.

Prompt injection has a CWE, and the two incidents everyone cites were not filed under it. That is not a clerical detail. A CWE ID is a claim about root cause, and every entry carries a mitigation table that follows from the root cause it names. When a record says CWE-1427, it is saying the product failed to neutralise input before building a prompt, and it is implying that neutralising the input is the fix.

A prompt injection test suite can only report on the payloads it contains. That sentence is the whole problem with the number most teams have. Somewhere in a ticket there is a scan result: a scanner threw several hundred probes at the endpoint and a percentage got through. The percentage is real.
