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

Description

Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.73.22 and 6.18.1, the Glide image proxy's URL validation could be bypassed using an IP representation that wasn't normalized before the public-IP check. An unauthenticated user could cause the server to make HTTP requests to internal addresses — including loopback, private network, and cloud metadata endpoints. This affects sites that pass user-supplied URLs to Glide. Sites running PHP 8.3 or newer are not affected. This vulnerability is fixed in 5.73.22 and 6.18.1.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update statamic/cms to 5.73.22 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-pf9c-ch8r-2958 is resolved across your whole dependency graph.

  3. Workarounds

    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.
