Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-16056 in the wild and no public exploit code.\n\nAffected product: Unknown Contest Gallery. 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-2026-16056/ (Markdown: https://insights.sbomify.com/CVE-2026-16056/index.md)","id":"CVE-2026-16056","markdown":"https://insights.sbomify.com/CVE-2026-16056/index.md","name":"CVE-2026-16056","record":{"aliases":["GHSA-xp5w-q4v3-mxrm"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated subscribers can read the site's entire stored OpenAI prompt history due to missing capability checks in the Contest Gallery plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"The Contest Gallery  WordPress plugin before 30.0.7 does not perform any capability or nonce check in one of its handlers, allowing any authenticated user down to Subscriber to read the site's entire stored OpenAI prompt history.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Contest Gallery \u003c 30.0.7 - Subscriber+ OpenAI Prompt History Disclosure via post_cg_get_openai_prompts","id":"CVE-2026-16056","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Contest Gallery \u003c 30.0.7 - Author+ Arbitrary Post Deletion via post_cg_youtube_delete_from_library","id":"CVE-2026-16057"},"packages":[],"prev":{"headline":"Contest Gallery \u003c 30.0.7 - Unauthenticated Login-Protection and 2FA Bypass via post_cg_login","id":"CVE-2026-16055"},"products":["Contest Gallery"],"published":"2026-08-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-04","vendors":["Unknown"]},"summary":"Authenticated subscribers can read the site's entire stored OpenAI prompt history due to missing capability checks in the Contest Gallery plugin.","url":"https://insights.sbomify.com/CVE-2026-16056/"}
