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 CVE-2026-15743 in the wild and no public exploit code.\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/CVE-2026-15743/ (Markdown: https://insights.sbomify.com/CVE-2026-15743/index.md)","id":"CVE-2026-15743","markdown":"https://insights.sbomify.com/CVE-2026-15743/index.md","name":"CVE-2026-15743","record":{"aliases":["DEBIAN-CVE-2026-15743","GHSA-cj6v-gcgr-8wgg","MGASA-2026-0393","UBUNTU-CVE-2026-15743"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl Catalyst plugin","requires_auth":"low_privilege","summary":"Attackers can access sensitive user data via shared caches because the plugin incorrectly marks authenticated responses as publicly cacheable.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[],"cvss":{"score":5.7,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-524","name":"Use of Cache Containing Sensitive Information"}],"description":"Catalyst::Plugin::Static::Simple versions through 0.38 for Perl mark responses as publicly cacheable.\n\nThe _serve_static method always sets the Cache-Control header to \"public\", with no means of overriding it.
