An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-46623 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.openidentityplatform.openam:openam-auth-oauth2 (Maven): affected all versions; fixed in 16.1.1\n- org.openidentityplatform.openam:openam-auth-oauth2 (Maven): affected all versions; fixed in 16.1.1\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-2026-46623/ (Markdown: https://insights.sbomify.com/CVE-2026-46623/index.md)","id":"CVE-2026-46623","markdown":"https://insights.sbomify.com/CVE-2026-46623/index.md","name":"CVE-2026-46623","record":{"aliases":["GHSA-gf57-4mp6-m85x","UBUNTU-CVE-2026-46623"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenAM access management","requires_auth":"none","summary":"Unauthenticated attackers can take over local accounts by exploiting missing attribute filtering in the OAuth2 module when account creation is enabled.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-620","name":"Unverified Password Change"},{"id":"CWE-1391","name":"Use of Weak Credentials"}],"description":"Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the OAuth2 authentication module updates an existing local account with profile attributes that can include userPassword and inetUserStatus, rewriting the password to the username and reactivating disabled accounts. The missing OAuth.removeRestrictedAccountUpdateAttributes filtering permits these credential and status fields to reach the account update. With account creation enabled, repeated OAuth login causes the default ldapService chain to accept the username as both identifier and password, allowing an unauthenticated attacker to take over the local account without interacting with the identity provider. The rewrite can be denied for usernames shorter than the configured minimum password length. This issue is fixed in version 16.1.1.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"OpenAM Account Takeover via Unverified Password Change in OAuth2 Module","id":"CVE-2026-46623","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":2,"n_references":3,"next":{"headline":"Twenty: SQL Injection via the timeZone field","id":"CVE-2026-46624"},"packages":[{"ecosystem":"Maven","fixed":["16.1.1"],"introduced":["0"],"last_affected":[],"package":"org.openidentityplatform.openam:openam-auth-oauth2","purl":null,"source":"GHSA-gf57-4mp6-m85x"},{"ecosystem":"Maven","fixed":["16.1.1"],"introduced":["0"],"last_affected":[],"package":"org.openidentityplatform.openam:openam-auth-oauth2","purl":"pkg:maven/org.openidentityplatform.openam/openam-auth-oauth2","source":"GHSA-gf57-4mp6-m85x"}],"prev":{"headline":"SolidInvoice: API tokens stored as plaintext in the database allowing full credential compromise on database breach","id":"CVE-2026-46622"},"products":["OpenAM"],"published":"2026-09-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-17","vendors":["OpenIdentityPlatform"]},"summary":"Unauthenticated attackers can take over local accounts by exploiting missing attribute filtering in the OAuth2 module when account creation is enabled.","url":"https://insights.sbomify.com/CVE-2026-46623/"}
