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-2026-88774 in the wild and no public exploit code.\n\nAffected product: Citrix 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-2026-88774/ (Markdown: https://insights.sbomify.com/CVE-2026-88774/index.md)","id":"CVE-2026-88774","markdown":"https://insights.sbomify.com/CVE-2026-88774/index.md","name":"CVE-2026-88774","record":{"aliases":["GHSA-m373-fcf4-9cxv"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Citrix NetScaler ADC","requires_auth":"none","summary":"Attackers can bypass feature policies in Citrix NetScaler ADC and Gateway due to improper HTTP URL expression handling.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NetScaler","cpe":[{"product":"netscaler_application_delivery_controller","vendor":"citrix"},{"product":"netscaler_gateway","vendor":"citrix"}],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:H/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Vulnerability in Citrix NetScaler ADC and Citrix NetScaler Gateway.\n\nThis issue affects ADC: before 14.1-73.37, before 13.1-64.23, before 14.1-73.37 FIPS, and before 13.1.37.279 FIPS and NDcPP; Gateway: before 14.1-73.37 and before 13.1-64.23 leading to a feature policy bypass due to improper HTTP URL based expression usage.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-10-23","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-10-23T23:39:04Z","kind":"github_poc","ref":"https://github.com/CompleteTech-Security/netscaler-cve-2026-88774-check","stars":0,"title":"Offline NetScaler ADC / Gateway evidence checker for CVE-2026-88774.
