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-2026-54364 in the wild and no public exploit code.\n\nAffected product: Gladinet CentreStack. 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-2026-54364/ (Markdown: https://insights.sbomify.com/CVE-2026-54364/index.md)","id":"CVE-2026-54364","markdown":"https://insights.sbomify.com/CVE-2026-54364/index.md","name":"CVE-2026-54364","record":{"aliases":["GHSA-g6j6-rqg9-wq7x"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"CentreStack file sharing","requires_auth":"none","summary":"Unauthenticated attackers can inject session variables to bypass authentication and access management pages in CentreStack.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"}],"description":"CentreStack before 17.4 contains a session variable injection vulnerability that allows unauthenticated attackers to inject arbitrary session variables by embedding newline and tab characters into a crafted AccountName parameter posted to the SelectProvider.aspx endpoint.
