An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-45775 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- discourse (Bitnami): affected from 2026.1.0; fixed in 2026.1.4, 2026.3.1, 2026.4.1\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-2026-45775/ (Markdown: https://insights.sbomify.com/CVE-2026-45775/index.md)","id":"CVE-2026-45775","markdown":"https://insights.sbomify.com/CVE-2026-45775/index.md","name":"CVE-2026-45775","record":{"aliases":["BIT-discourse-2026-45775","GHSA-5j6v-4x6g-9pg5"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Discourse forum platform","requires_auth":"high_privilege","summary":"An authenticated administrator in a multisite Discourse deployment can access backup files from other sites via path traversal.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"discourse","vendor":"discourse"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Discourse is an open-source discussion platform.
