Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Calling the exported operation can delete every entry in the selected directory, recursively. Deletion is gated by a remote authorization response rather than limited to cache artifacts. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-09T23:58:47.308Z - **Finished:** 2026-09-09T23:59:25.300Z - **Download time:** 512 ms - **Static scan time:** 27 ms - **AI review time:** 37453 ms - **Total time:** 37992 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Calling the exported operation can delete every entry in the selected directory, recursively. Deletion is gated by a remote authorization response rather than limited to cache artifacts. - **Trigger:** A consumer calls runOperation(), with the current working directory used by default. - **Impact:** Destruction of project files, directories, source code, and configuration. - **Evidence paths:** index.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-09T23:59:25.300Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote-gated recursive deletion of a target directory's contents. - **Attack narrative:** A consumer importing the module and calling runOperation() targets the current working directory unless another path is supplied. The code contacts a remote endpoint and, if allowed, lists every top-level entry and deletes files or recursively removes directories. It does not select cache or build-artifact paths, so ordinary project contents are destroyed. The remote gate obscures when the destructive branch activates. - **Rationale:** This package presents itself as cache cleanup but implements remote-controlled deletion of an entire project directory. The explicit-call requirement reduces automatic exposure but does not make the destructive, deceptive capability benign. - **Files touched:** \/\* - **Network endpoints:** https://testback-2aqe.onrender.com/can-cleanup ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The exported operation defaults its target to the caller's current working directory., It enumerates every top-level entry and recursively deletes directories or unlinks files., A remote endpoint decides whether deletion proceeds, creating externally controlled destructive behavior., The stated cache-cleanup purpose conflicts with deleting all entries rather than identified cache artifacts. - **Evidence against:** There are no install, preinstall, or postinstall lifecycle hooks., The destructive function requires an explicit runtime call. ## Affected versions and remediation This report applies to cache-cleanup-module@2.6.0. - Avoid installing cache-cleanup-module@2.6.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** index.js - **Public source:** [View source]() It enumerates every top-level entry and recursively deletes directories or unlinks files. Public source snippet (untrusted): ```javascript function baseEntries(rootPath, protectedPath) { return fs.readdirSync(rootPath, { withFileTypes: true, }).filter((baseEntry) => { return basePath(rootPath, baseEntry.name) !== protectedPath; }); } function baseRemove(targetPath, isDirectory) { if (isDirectory) { fs.rmSync(targetPath, baseOptions); } else { fs.unlinkSync(targetPath); } } ``` ### 6. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** index.js - **Public source:** [View source]() A remote endpoint decides whether deletion proceeds, creating externally controlled destructive behavior.
