An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-107842 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- contao/core-bundle (Packagist): affected from 4.0.0; fixed in 5.3.50\n- contao/core-bundle (Packagist): affected from 4.0.0; fixed in 5.3.50\n- contao/core-bundle (Packagist): affected from 5.4.0-RC1; fixed in 5.7.12\n- contao/core-bundle (Packagist): affected from 5.4.0-RC1; fixed in 5.7.12\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-2026-107842/ (Markdown: https://insights.sbomify.com/CVE-2026-107842/index.md)","id":"CVE-2026-107842","markdown":"https://insights.sbomify.com/CVE-2026-107842/index.md","name":"CVE-2026-107842","record":{"aliases":["GHSA-x2rp-9qf7-2fmq"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Contao CMS","requires_auth":"none","summary":"Disabling protected page indexing in Contao CMS leaks protected page titles and snippets to anonymous users via search results.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Contao is an Open Source CMS. From version 4.0.0 until 5.3.50 and 5.7.12, ModuleSearch can disclose protected page titles, URLs, and indexed context snippets to unauthenticated visitors when contao.search.index_protected is changed from enabled to disabled. Authorization metadata is stored per row in tl_search, but disabling the setting removes the protected-row filter without deleting rows indexed while protection was enabled. The protected pages continue to return an authorization response, so this issue exposes search metadata and indexed text rather than bypassing page access.
