Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-90989 in the wild and no public exploit code.\n\nAffected product: Unknown Tainacan. 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-2026-90989/ (Markdown: https://insights.sbomify.com/CVE-2026-90989/index.md)","id":"CVE-2026-90989","markdown":"https://insights.sbomify.com/CVE-2026-90989/index.md","name":"CVE-2026-90989","record":{"aliases":["GHSA-wj3w-gf2c-jjrc"],"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 access staff email addresses via unrestricted REST endpoints in the Tainacan WordPress plugin.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"The Tainacan WordPress plugin before 1.4.0 does not restrict its reports REST endpoints to users with a management capability, allowing any authenticated subscriber to read the email addresses of the repository's staff.","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":"Tainacan \u003c 1.4.0 - Subscriber+ Repository Staff Email Address Disclosure via Reports REST Endpoints","id":"CVE-2026-90989","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Livestatus injection via monitoring filter values","id":"CVE-2026-90990"},"packages":[],"prev":{"headline":"Request a Quote \u003c= 2.5.6 - Unauthenticated Quote Request Contact Record Disclosure via emd_get_std_pagenum","id":"CVE-2026-90988"},"products":["Tainacan"],"published":"2026-10-14","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":"2026-10-15","vendors":["Unknown"]},"summary":"Authenticated subscribers can access staff email addresses via unrestricted REST endpoints in the Tainacan WordPress plugin.","url":"https://insights.sbomify.com/CVE-2026-90989/"}
