An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-3055 in the wild since at least 30 Mar 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-2026-3055/ (Markdown: https://insights.sbomify.com/CVE-2026-3055/index.md)","id":"CVE-2026-3055","markdown":"https://insights.sbomify.com/CVE-2026-3055/index.md","name":"CVE-2026-3055","record":{"aliases":["GHSA-wv7p-q4p2-p6pf"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"NetScaler ADC Gateway","requires_auth":"none","summary":"Attackers can read sensitive memory contents from NetScaler devices configured as SAML IDPs due to insufficient input validation.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NetScaler","cpe":[{"product":"netscaler_application_delivery_controller","vendor":"citrix"},{"product":"netscaler_gateway","vendor":"citrix"}],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:L/SI:L/SA:L","version":"4.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Insufficient input validation in NetScaler ADC and NetScaler Gateway when configured as a SAML IDP leading to memory overread","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-03-23","github_poc":5,"max_poc_stars":1,"metasploit":1,"nuclei":1,"refs":[{"date":"2026-03-31T16:07:38Z","kind":"github_poc","ref":"https://github.com/fevar54/CVE-2026-3055---Citrix-NetScaler-Memory-Overread-PoC","stars":1,"title":"PoC de CVE-2026-3055: memory overread en Citrix NetScaler ADC/Gateway para filtrar session IDs."},{"date":"2026-03-31T16:23:12Z","kind":"github_poc","ref":"https://github.com/fevar54/CVE-2026-3055-Scanner---Herramienta-de-Detecci-n","stars":1,"title":"Scanner de CVE-2026-3055: detecta NetScaler ADC/Gateway vulnerables a memory overread.
