CVE-2022-39381 is a high-severity null pointer dereference vulnerability in muhammara (npm), affecting versions < 2.6.0. It is fixed in 2.6.0, 1.0.111.
Impact The package muhammara before 2.6.0; all versions of package hummus are vulnerable to Denial of Service (DoS) when supplied with a maliciously crafted PDF file to be appended to another. Patches It has been patched in 2.6.0 for muhammara and not at all for hummus Workarounds Do not process files from untrusted sources References PR: https://github.com/julianhille/MuhammaraJS/pull/194 Issue: https://github.com/julianhille/MuhammaraJS/issues/191 Issue in hummus: https://github.com/galkahana/HummusJS/issues/293 Outline differences to https://nvd.nist.gov/vuln/detail/CVE-2022-25892 The difference is one is in src/deps/PDFWriter/PDFParser.cpp and the other is PDFDocumentHandler.cpp both is a null pointer but for different cases These are totally diffent issues, one is in reading a pdf the other is in appendending a maliciously crafted one. The function calls are different the versions in which they are solved are diffent.
The application dereferences a null pointer, causing a crash. Typical impact: denial of service via crash.
CVE-2022-39381 has a CVSS score of 7.5 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment.
A fixed version is available (2.6.0, 1.0.111). Upgrading removes the vulnerable code path.

Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter instead of chasing every advisory.
Kodem's runtime-powered SCA identifies whether CVE-2022-39381 is reachable in your applications. Explore open-source security for your team.

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
