Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-1554 in the wild and no public exploit code.\n\nAffected product: Drupal Central Authentication System (CAS) Server. 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-2026-1554/ (Markdown: https://insights.sbomify.com/CVE-2026-1554/index.md)","id":"CVE-2026-1554","markdown":"https://insights.sbomify.com/CVE-2026-1554/index.md","name":"CVE-2026-1554","record":{"aliases":["DRUPAL-CONTRIB-2026-007","GHSA-rgcm-m74w-vrfx"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Drupal CAS module","requires_auth":"low_privilege","summary":"An XML injection vulnerability in the Drupal CAS Server module allows attackers to escalate privileges.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"drupal","cpe":[{"product":"central_authentication_system_server","vendor":"jtenman"}],"cvss":{"score":4.2,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-91","name":"XML Injection"}],"description":"XML Injection (aka Blind XPath Injection) vulnerability in Drupal Central Authentication System (CAS) Server allows Privilege Escalation.This issue affects Central Authentication System (CAS) Server: from 0.0.0 before 2.0.3, from 2.1.0 before 2.1.2.","ecosystems":["Packagist:https://packages.drupal.org/8"],"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":"Central Authentication System (CAS) Server - Less critical - XML Element Injection - SA-CONTRIB-2026-007","id":"CVE-2026-1554","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xxe","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"WebStack \u003c= 1.2024 - Unauthenticated Arbitrary File Upload","id":"CVE-2026-1555"},"packages":[{"ecosystem":"Packagist:https://packages.drupal.org/8","fixed":["2.0.3","2.1.2"],"introduced":["0","2.1.0"],"last_affected":[],"package":"drupal/cas_server","purl":"pkg:composer/drupal/cas_server?repository_url=https:%2F%2Fpackages.drupal.org%2F8","source":"DRUPAL-CONTRIB-2026-007"}],"prev":{"headline":"Drupal Canvas - Moderately critical - Access bypass - SA-CONTRIB-2026-006","id":"CVE-2026-1553"},"products":["Central Authentication System (CAS) Server"],"published":"2026-02-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"MIT","name":"Drupal","prefix":"DRUPAL"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"2026-02-05","vendors":["Drupal"]},"summary":"An XML injection vulnerability in the Drupal CAS Server module allows attackers to escalate privileges.","url":"https://insights.sbomify.com/CVE-2026-1554/"}
