Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to beaver-ui-form@34.9.1. - Avoid installing beaver-ui-form@34.9.1. 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: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% Package advertises itself as a React UI toolkit but on require(), \_helpers.js runs init() at module load which selects a platform-specific URL, fetches a native binary over HTTPS from obfuscated Cloudflare Workers subdomains (oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev), writes it to /tmp under a disguised name (.cache\_\) on Linux/macOS or to %TEMP% as dotnet\_diag\_\.exe on Windows, chmods 755, and spawns it detached via /bin/sh -c or cmd.exe (\_helpers.js:122-128). C2 hostnames are constructed via array-join string splits to evade static analysis, stderr is suppressed by a no-op wrapper, and DISABLE\_TELEMETRY/ANALYTICS\_OPT\_OUT/DO\_NOT\_TRACK environment checks provide a telemetry cover story. If the HTTPS retrieval fails, the code falls back to a DNS-TXT covert channel: it resolves TXT records at c.\.dl.wel1.ru for a chunk count, iterates 0..N.\.dl.wel1.ru TXT records (sdk/ext/pkg/net.dl.wel1.ru), base64-decodes the concatenation into a payload buffer, writes it to disk and executes it. Result is full-host remote code execution on any developer machine or CI runner that installs and requires the package. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** beaver-ui-form - **Ecosystem:** npm - **Version:** 34.9.1 - **Version published:** 2026-08-03T04:57:23.639Z - **Package first seen:** 2026-08-04T22:30:08.797Z - **Package last seen:** 2026-08-04T22:30:08.797Z - **Known versions:** 1 - **Latest version:** 34.9.1 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]()
