An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-8452 in the wild since at least 26 Aug 2026.\n\nAffected product: NetScaler ADC. 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-2026-8452/ (Markdown: https://insights.sbomify.com/CVE-2026-8452/index.md)","id":"CVE-2026-8452","markdown":"https://insights.sbomify.com/CVE-2026-8452/index.md","name":"CVE-2026-8452","record":{"aliases":["GHSA-r7wg-r5wj-c765"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"NetScaler ADC Gateway","requires_auth":"none","summary":"Attackers can cause denial of service via memory overflow in NetScaler ADC and Gateway when configured as a Gateway or AAA virtual server.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NetScaler","cpe":[{"product":"netscaler_application_delivery_controller","vendor":"citrix"},{"product":"netscaler_gateway","vendor":"citrix"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:H/SC:L/SI:L/SA:L","version":"4.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Memory overflow vulnerability NetScaler ADC and NetScaler Gateway leading to unpredictable or erroneous behavior and Denial of Service if the appliance is configured as a Gateway (SSL VPN, ICA Proxy, CVPN, RDP Proxy) or AAA virtual server","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2023-07-20","github_poc":5,"max_poc_stars":96,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-07-20T16:05:07Z","kind":"github_poc","ref":"https://github.com/securekomodo/citrixInspector","stars":96,"title":"Passively fingerprint Citrix ADC / NetScaler ADC \u0026 Gateway builds and detect known CVEs — CVE-2023-3519, CitrixBleed 2/3, CVE-2026-8452, and CVE-2026-88771/88772 (KEV)"},{"date":"2026-08-14T15:01:25Z","kind":"github_poc","ref":"https://github.com/watchtowrlabs/watchTowr-vs-Citrix-Netscaler-PreAuth-RCE-CVE-2026-8452","stars":65,"title":"CVE-2026-8452 PreAuth RCE"},{"date":"2026-08-20T11:24:44Z","kind":"github_poc","ref":"https://github.com/BishopFox/CVE-2026-8452-check","stars":1,"title":"Safely detect Citrix NetScaler CVE-2026-8452"},{"date":"2026-08-30T13:19:58Z","kind":"github_poc","ref":"https://github.com/maxprog-svg/CitrixBleedCVE-2026-8452-2025-5777","stars":0,"title":"CitrixBleed Exploit Tool - CVE-2025-5777 \u0026 CVE-2026-8452.
