How severe is CVE-2026-44439?

No CVSS score has been assigned to CVE-2026-44439 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2026-44439?

CVE-2026-44439 affects the following packages: playwrightcapture (PyPI). Ecosystems affected: PyPI.

How do I fix CVE-2026-44439?

Update playwrightcapture to 1.39.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-44439 is resolved across your whole dependency graph.

How do I detect CVE-2026-44439 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for playwrightcapture, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2026-44439 if there is no patch (or I can't update yet)?

Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated.

Is CVE-2026-44439 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-44439 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-44439?

CVE-2026-44439 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 34th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2026-44439?

CVE-2026-44439 is classified as Server-Side Request Forgery (SSRF) (CWE-918). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2026-44439 published, and has it been updated?

CVE-2026-44439 was published on May 13, 2026 and was last updated on October 28, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.

Description

Playwright Capture did not sufficiently restrict navigations and resource requests initiated by rendered pages. An attacker-controlled page could abuse browser-side redirection mechanisms, such as window.location.href, to make the capture process open file:// URLs or request resources hosted on private, loopback, link-local, or otherwise non-public IP addresses. In deployments where PlaywrightCapture processes untrusted URLs, this could allow a remote attacker to perform server-side request forgery against internal services or attempt to access local files from the capture environment. Depending on what capture artifacts are generated and exposed, responses from those resources could potentially be leaked through screenshots, saved page content, logs, or other capture outputs. The patch mitigates the issue by introducing request routing checks that block secondary requests to local files, non-global IP addresses, and .local domains when only_global_lookup is enabled, while still allowing the originally requested capture URL.
