How severe is GHSA-cwcx-382v-8m9g?

No CVSS score has been assigned to GHSA-cwcx-382v-8m9g yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-cwcx-382v-8m9g?

GHSA-cwcx-382v-8m9g affects the following packages: weblate (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-cwcx-382v-8m9g?

Update weblate to 5.17.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-cwcx-382v-8m9g is resolved across your whole dependency graph.

How do I detect GHSA-cwcx-382v-8m9g in my PyPI dependencies?

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

How do I mitigate GHSA-cwcx-382v-8m9g 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 GHSA-cwcx-382v-8m9g actively exploited in the wild?

No public exploit code has been indexed for GHSA-cwcx-382v-8m9g 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 GHSA-cwcx-382v-8m9g?

GHSA-cwcx-382v-8m9g has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 31th 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 GHSA-cwcx-382v-8m9g?

GHSA-cwcx-382v-8m9g is classified as Improper Input Validation (CWE-20), Server-Side Request Forgery (SSRF) (CWE-918). These weakness types 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 GHSA-cwcx-382v-8m9g published, and has it been updated?

GHSA-cwcx-382v-8m9g was published on April 30, 2026 and was last updated on July 13, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Impact

An authenticated user with project.add permission (default on hosted Weblate SaaS and for any user holding an active billing/trial plan) can import a crafted project backup ZIP whose components/<name>.json contains an attacker-chosen repo URL pointing at a private address (e.g. http://127.0.0.1:9999/) or using a non-allow-listed scheme (e.g. file://, git://). Weblate persists the component via Component.objects.bulk_create([component])[0], which bypasses Django's full_clean() and therefore never runs the validate_repo_url validator. The URL is subsequently written verbatim into .git/config by configure_repo(pull=False).
