The server previously accepted this parameter value and processed the request with defaults. The uncertainty is that the patch does not explicitly describe an active tampering scenario; it is a server-side validation gap. CAPEC-124 is selected as the best available match because the core mechanism is the manipulation of a request parameter to reference an unauthorized resource."

It requires a low-privilege authenticated user (PR:L) and no user interaction (UI:N). The primary impact is a low confidentiality impact (VC:L) because an authenticated user could trigger processing through a module not in the enabled set, potentially exposing data or processing results not intended to be available. No integrity or availability impact is evidenced (VI:N, VA:N). No secondary impacts are indicated (SC:N, SI:N, SA:N). The low impact reflects that the user already has authenticated access to the event and the exposure is limited to an additional module processing path.",

In this case, a site admin specifies a blocklist filename with a dangerous extension (e.g., .php) that is placed in the MISP export directory. The mechanism is not a traditional multipart upload but rather a workflow parameter that results in a file being written to a web-accessible location. CAPEC-170 is the closest available pattern; the uncertainty is that the file is not uploaded via a standard upload endpoint but is instead referenced by name in a workflow action, making the mapping approximate."

The exploit has been disclosed publicly and may be used. In v2.9.0 the PyTorch tensor load path is hardened (weights_only=True), but that hardening was later reverted on master via PR #1913 \"Hotfix: revert loading with weights_only=True\" [blocked] to fix PyTorch 1.13 compat - so even the one \"safe\" path is inconsistent across versions. #2281 was closed as a duplicate of #1831 since both are unsafe pickle deserialization - but #1831\u0027s fix (PR #41) only gated the Hugging Face Hub loader in the separate huggingface_sb3 package. This finding covers the core stable_baselines3 load APIs (PPO.load, load_replay_buffer, VecNormalize.load), which have no safe mode or gate and remained exploitable in v2.9.0 until the outstanding hardening (PR #2264) ships."
