An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-27790 in the wild and no public exploit code.\n\nAffected product: Gallagher T-20 Readers. 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-2026-27790/ (Markdown: https://insights.sbomify.com/CVE-2026-27790/index.md)","id":"CVE-2026-27790","markdown":"https://insights.sbomify.com/CVE-2026-27790/index.md","name":"CVE-2026-27790","record":{"aliases":["GHSA-56pq-38g7-f784"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Access control reader","requires_auth":"high_privilege","summary":"An authenticated operator can trigger a temporary denial of service on Gallagher T-20 Readers by sending specific requests that cause an uncaught exception.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gallagher","cpe":[{"product":"command_centre","vendor":"gallagher"}],"cvss":{"score":2.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-248","name":"Uncaught Exception"}],"description":"Uncaught Exception (CWE-248) in the T20 Readers allows an authenticated and authorized operator to trigger a restart by sending specific requests, resulting in a temporary denial of service. Version of Command Centre affected:\n\n  *  9.50 prior to vCR9.50.260616a (distributed in 9.50.1587(MR1))\n  *  9.40 prior to vCR9.40.260616a (distributed in 9.40.3130(MR3))\n  *  9.30 prior to vCR9.30.260616a (distributed in 9.30.3983(MR5))\n  *  9.20 prior to vCR9.20.260616a (distributed in 9.20.4349(MR7))\n  *  all versions of 9.10 and prior.","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":"Denial of service in T-20 Readers","id":"CVE-2026-27790","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Seerr missing authentication on pushSubscription endpoints","id":"CVE-2026-27792"},"packages":[],"prev":{"headline":"Privilege escalation in ServerView Agents for Windows","id":"CVE-2026-27788"},"products":["T-20 Readers"],"published":"2026-07-07","related":[{"cvss_score":9.9,"headline":"Missing authorization in Command Centre","id":"CVE-2021-23140","kev_date_added":null,"published":"2021-06-11"},{"cvss_score":9.9,"headline":"SQL injection in Command Centre","id":"CVE-2021-23230","kev_date_added":null,"published":"2021-06-11"},{"cvss_score":9.9,"headline":"Missing authorization in Command Centre","id":"CVE-2020-16096","kev_date_added":null,"published":"2020-09-15"},{"cvss_score":9.8,"headline":"Information disclosure in Command Centre","id":"CVE-2020-16098","kev_date_added":null,"published":"2020-09-15"},{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2019-15294","kev_date_added":null,"published":"2019-08-28"},{"cvss_score":9.1,"headline":"Information disclosure in Command Centre Server","id":"CVE-2024-21815","kev_date_added":null,"published":"2024-03-05"},{"cvss_score":8.8,"headline":"Memory corruption in Command Centre","id":"CVE-2020-16103","kev_date_added":null,"published":"2020-12-14"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-07-07","vendors":["Gallagher"]},"summary":"An authenticated operator can trigger a temporary denial of service on Gallagher T-20 Readers by sending specific requests that cause an uncaught exception.","url":"https://insights.sbomify.com/CVE-2026-27790/"}
