This weakness is formally classified as CWE\u2011843, Access of Resource Using Incompatible Type.

This high severity score indicates significant risk despite the low likelihood of exploitation. Because no official patch or workaround is cited in the provided references, an affected organization would need to rely on its own safeguards. The likely attack vector would involve an attacker interacting with the Uppy service\u2014most plausibly by supplying a crafted upload or request that triggers the type mismatch. The absence of a listed exploit in KEV suggests no publicly known active exploit, but the undefined behavior inherent in this class of bug warrants caution."}}}}, "created": "2026-04-15T14:41:09.665870+00:00", "updated": "2026-04-17T08:30:13.703351+00:00", "vendors": ["transloadit", "transloadit$PRODUCT$uppy"]}
