Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-15571 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- keycloak (Bitnami): affected all versions; fixed in 26.7.2\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-2026-15571/ (Markdown: https://insights.sbomify.com/CVE-2026-15571/index.md)","id":"CVE-2026-15571","markdown":"https://insights.sbomify.com/CVE-2026-15571/index.md","name":"CVE-2026-15571","record":{"aliases":["BIT-keycloak-2026-15571","GHSA-m639-f4cw-m3hm"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Identity and Access Management","requires_auth":"low_privilege","summary":"Attackers can predict account-linking hashes to forge URLs, enabling full account takeover of victims via malicious OIDC clients in Keycloak.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-341","name":"Predictable from Observable State"}],"description":"A flaw was found in the legacy client-initiated account-linking endpoint of Keycloak, a widely used open-source identity and access management solution. The mechanism used to protect the account-linking process from unauthorized requests relies on a hash that can be predicted by a malicious OIDC client. By tricking a user into authenticating, an attacker-controlled client can forge a valid linking URL to connect the victim's account to an attacker's external identity. This results in a full account takeover, allowing the attacker to log in as the victim.","ecosystems":["Bitnami"],"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":"Auth bypass in Red Hat Data Grid 8","id":"CVE-2026-15571","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":1,"n_references":4,"next":{"headline":"Keycloak-services: keycloak-services: dcr protocol mapper type-swap policy bypass allows privilege escalation","id":"CVE-2026-15572"},"packages":[{"ecosystem":"Bitnami","fixed":["26.7.2"],"introduced":["0"],"last_affected":[],"package":"keycloak","purl":"pkg:bitnami/keycloak","source":"BIT-keycloak-2026-15571"}],"prev":{"headline":"Improper URL Scheme and Destination Validation in SmartCenter browserseturl Command","id":"CVE-2026-15570"},"products":["Red Hat Data Grid 8","Red Hat JBoss Enterprise Application Platform Expansion Pack","Red Hat Single Sign-On 7","Red Hat build of Keycloak 26.6","Red Hat build of Keycloak 26.6.6"],"published":"2026-08-18","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"2026-08-20","vendors":["Red Hat"]},"summary":"Attackers can predict account-linking hashes to forge URLs, enabling full account takeover of victims via malicious OIDC clients in Keycloak.","url":"https://insights.sbomify.com/CVE-2026-15571/"}
