ezsystems/ezplatform-http-cache affected by Breach with Varnish VCL
Real-World Exposure
ezsystems/ezplatform-http-cacheReal-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
Impact
This is not a vulnerability in the code per se, but included Varnish VCL templates enable compression of API and JSON messages. This is a potential case of the BREACH vulnerability, which affects HTTP compression, where secrets can be extracted through carefully crafted requests. The fix disables compression in these templates. Please make sure to make the same change in your configuration files, see the release notes for specific instructions. Please check your web server configuration as well.
Patches
- See "Patched versions".
- https://github.com/ezsystems/ezplatform-http-cache/commit/ca8a5cf69b2c14fbec90412aeeef5c755c51457b
Workarounds
Make sure HTTP compression is disabled for REST API requests and other communication that might contain secrets.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ezsystems/ezplatform-http-cache, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update ezsystems/ezplatform-http-cache to 2.3.16 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mgfg-7533-7jf6 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-mgfg-7533-7jf6 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-mgfg-7533-7jf6. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-mgfg-7533-7jf6 in your dependencies?
O3 Security finds GHSA-mgfg-7533-7jf6 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
