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-2026-73191 in the wild and no public exploit code.\n\nAffected product: Apache Syncope. 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-2026-73191/ (Markdown: https://insights.sbomify.com/CVE-2026-73191/index.md)","id":"CVE-2026-73191","markdown":"https://insights.sbomify.com/CVE-2026-73191/index.md","name":"CVE-2026-73191","record":{"aliases":["GHSA-f668-p5f8-gcxm"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Syncope","requires_auth":"none","summary":"Attackers can redirect users to malicious sites via crafted HTTP headers when CAS authentication is enabled in Apache Syncope.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"URL Redirection to Untrusted Site ('Open Redirect') vulnerability in Apache Syncope.\n\nWhen the Syncope SRA is configured for CAS authentication, the target Apereo CAS instance's URL is calculated by unconditionally looking at client-supplied forwarded HTTP headers.\n\nThis issue affects Apache Syncope: from 3.0.0-M0 through 3.0.16, from 4.0.0-M0 Through 4.0.7, from 4.1.0-M0 through 4.1.2.\n\nUsers are recommended to upgrade to version 4.0.8 / 4.1.3, which fix this issue.","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":"Apache Syncope: CAS service URL injection via Forwarded HTTP headers","id":"CVE-2026-73191","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"open_redirect","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache Sling XSS: XSS possible through XSSAPI.getValidHref()","id":"CVE-2026-73192"},"packages":[],"prev":{"headline":"WordPress WPDM – Premium Packages plugin \u003c= 7.0.5 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2026-73190"},"products":["Apache Syncope"],"published":"2026-09-14","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":"2026-09-14","vendors":["Apache Software Foundation"]},"summary":"Attackers can redirect users to malicious sites via crafted HTTP headers when CAS authentication is enabled in Apache Syncope.","url":"https://insights.sbomify.com/CVE-2026-73191/"}
