Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-125870 in the wild and no public exploit code.\nExposure: An affected version is exposed as installed. No special setting or call is needed.\n\nAffected product: bookstackapp bookstack. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-125870/ (Markdown: https://insights.sbomify.com/CVE-2026-125870/index.md)","id":"CVE-2026-125870","markdown":"https://insights.sbomify.com/CVE-2026-125870/index.md","name":"CVE-2026-125870","record":{"aliases":["GHSA-pwxm-hjwv-54xf"],"analysis":{"component_type":"web_application","exploitable_when_present":false,"fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"wiki platform","requires_auth":"low_privilege","requires_specific_call":false,"summary":"Authenticated non-admin BookStack users can view metadata of restricted images and rename, replace or delete them, persisting content they cannot see.","user_interaction":"not_required","vuln_class":"missing_authorization","vulnerable_functions":["ImageController::checkImagePermission()"]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"VulnCheck","cpe":[],"cvss":{"score":2.3,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"BookStack before 26.09.3 contains a missing authorization vulnerability in ImageController::checkImagePermission() that allows authenticated non-admin users to bypass page-level content restrictions for images whose owning page has been moved to the recycle bin, because the permission check relies on Page::getPage() which returns null for soft-deleted pages and silently skips the PageView check.
