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-2026-78617 in the wild and no public exploit code.\n\nAffected product: WatchGuard Dimension. 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-2026-78617/ (Markdown: https://insights.sbomify.com/CVE-2026-78617/index.md)","id":"CVE-2026-78617","markdown":"https://insights.sbomify.com/CVE-2026-78617/index.md","name":"CVE-2026-78617","record":{"aliases":["GHSA-3x89-jjqx-2x3q"],"analysis":{"component_type":"web_application","fix_type":"configuration_change","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"WatchGuard Dimension","requires_auth":"none","summary":"Remote attackers can brute-force user accounts on WatchGuard Dimension due to missing default rate limiting, requiring configuration changes to enable account lockout.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WatchGuard","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"},{"id":"CWE-203","name":"Observable Discrepancy"}],"description":"WatchGuard Dimension's web login endpoint does not enforce effective rate-limiting or account lockout by default allowing a remote attacker to perform automated password guessing against user accounts.
