An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of DRUPAL-CONTRIB-2019-004 in the wild and no public exploit code.\n\nAffected product: drupal/preview_link. 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/DRUPAL-CONTRIB-2019-004/ (Markdown: https://insights.sbomify.com/DRUPAL-CONTRIB-2019-004/index.md)","id":"DRUPAL-CONTRIB-2019-004","markdown":"https://insights.sbomify.com/DRUPAL-CONTRIB-2019-004/index.md","name":"DRUPAL-CONTRIB-2019-004","record":{"aliases":[],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Drupal Preview Link module","requires_auth":"none","summary":"Attackers can bypass access controls to view unpublished content by presenting invalid tokens in the Preview Link module.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The Preview Link module enables you to generate preview links so anonymous users can access unpublished revisions of content.  \nThe last release of the module introduced an access bypass allowing users to present invalid tokens but still access unpublished content.","ecosystems":["Packagist:https://packages.drupal.org/8"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"The Preview Link module enables you to generate preview links so anonymous users can access unpublished revisions of content.","id":"DRUPAL-CONTRIB-2019-004","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2019"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"Packagist:https://packages.drupal.org/8","fixed":["1.1.0"],"introduced":["0"],"last_affected":[],"package":"drupal/preview_link","purl":"pkg:composer/drupal/preview_link?repository_url=https:%2F%2Fpackages.drupal.org%2F8","source":"DRUPAL-CONTRIB-2019-004"}],"products":null,"published":"2019-01-23","related":[],"sources":[{"class":"attribution","licence":"MIT","name":"Drupal","prefix":"DRUPAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Attackers can bypass access controls to view unpublished content by presenting invalid tokens in the Preview Link module.","url":"https://insights.sbomify.com/DRUPAL-CONTRIB-2019-004/"}
