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-2026-82183 in the wild and no public exploit code.\n\nAffected product: Unknown OAuth Single Sign On. 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-2026-82183/ (Markdown: https://insights.sbomify.com/CVE-2026-82183/index.md)","id":"CVE-2026-82183","markdown":"https://insights.sbomify.com/CVE-2026-82183/index.md","name":"CVE-2026-82183","record":{"aliases":["GHSA-f9w9-q3c6-p58g"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can bypass Steam OpenID verification to log in as arbitrary users or create new accounts in the OAuth Single Sign On plugin.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The OAuth Single Sign On  WordPress plugin before 7.0.1 does not verify the identity assertion returned by its Steam single sign-on flow, allowing unauthenticated attackers to log in as an arbitrary non-administrator user, and to create new accounts.","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":"OAuth Single Sign On 6.25.0 - 7.0.0 - Unauthenticated Account Takeover via Unverified Steam OpenID Assertion","id":"CVE-2026-82183","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"WPLP Cookie Consent \u003c 4.4.2 - Unauthenticated IAB TCF Consent Option Update","id":"CVE-2026-82184"},"packages":[],"prev":{"headline":"WPvivid Backup \u0026 Migration \u003c 0.9.133 - Admin+ SQLi via Upload Cleaner Isolation","id":"CVE-2026-82182"},"products":["OAuth Single Sign On"],"published":"2026-09-02","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":"total"},"state":"PUBLISHED","updated":"2026-09-02","vendors":["Unknown"]},"summary":"Unauthenticated attackers can bypass Steam OpenID verification to log in as arbitrary users or create new accounts in the OAuth Single Sign On plugin.","url":"https://insights.sbomify.com/CVE-2026-82183/"}
