Malicious code in @kxafunc/xbails (npm)

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

--- _-= Per source details.

On every install, npm resolves this alias to whatever bytes `@bellaxchuu/libsignal-node` currently publishes, and the resolved module is loaded by `lib/Signal/libsignal.js` and `lib/Utils/crypto.js`, providing the Signal end-to-end cryptographic primitives (SessionCipher, SessionBuilder, ProtocolAddress, SessionRecord) with access to identity keys, prekeys, and plaintext messages. Whoever controls that upstream package name can push arbitrary code into every installer at any time, executing inside the Signal E2E encrypt/decrypt path. This is an off-registry-style trust relationship: the manifest itself constitutes the exposure, independent of what the current contents of the alias target happen to be.
