Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of GHSA-4h8f-c635-25p7 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- ibexa/post-install (Packagist): affected from 1.0.0; fixed in 1.0.16\n- ibexa/post-install (Packagist): affected from 1.0.0; fixed in 1.0.16\n- ibexa/post-install (Packagist): affected from 4.6.0; fixed in 4.6.14\n- ibexa/post-install (Packagist): affected from 4.6.0; fixed in 4.6.14\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/GHSA-4h8f-c635-25p7/ (Markdown: https://insights.sbomify.com/GHSA-4h8f-c635-25p7/index.md)","id":"GHSA-4h8f-c635-25p7","markdown":"https://insights.sbomify.com/GHSA-4h8f-c635-25p7/index.md","name":"GHSA-4h8f-c635-25p7","record":{"aliases":[],"analysis":{"component_type":"server_software","fix_type":"configuration_change","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Ibexa post-install templates","requires_auth":"low_privilege","summary":"Attackers can extract secrets from HTTP responses via BREACH attack due to enabled compression in default Varnish and web server templates.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"### Impact\nThis is not a vulnerability in the code per se, but included platform.sh Varnish VCL templates and Apache/Nginx vhost 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.
