An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-16551 in the wild and no public exploit code.\n\nAffected product: Thinkst Applied Research OpenCanary. 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-2026-16551/ (Markdown: https://insights.sbomify.com/CVE-2026-16551/index.md)","id":"CVE-2026-16551","markdown":"https://insights.sbomify.com/CVE-2026-16551/index.md","name":"CVE-2026-16551","record":{"aliases":["GHSA-vg37-pc42-q265"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenCanary honeypot","requires_auth":"none","summary":"An attacker can cause a denial of service in OpenCanary's MongoDB module through excessive allocation, affecting system availability.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ThinkstAppliedResearch","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/S:N","version":"4.0"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Denial-of-Service in Thinkst Applied Research OpenCanary (MongoDB module) allows Excessive Allocation.\n\nThis issue affects OpenCanary 0.9.8 only.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Denial-of-Service in OpenCanary's MongoDB module","id":"CVE-2026-16551","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":"The reported issue is invalid, as it requires root privileges to reproduce, and it is out of scope of the threat model of the affected component.","id":"CVE-2026-16552"},"packages":[],"prev":{"headline":"Bit Assist \u003c 1.8.2 - Unauthenticated Arbitrary File Upload via Response Endpoint","id":"CVE-2026-16548"},"products":["OpenCanary"],"published":"2026-07-22","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":"2026-07-22","vendors":["Thinkst Applied Research"]},"summary":"An attacker can cause a denial of service in OpenCanary's MongoDB module through excessive allocation, affecting system availability.","url":"https://insights.sbomify.com/CVE-2026-16551/"}
