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-2026-15689 in the wild and no public exploit code.\n\nAffected product: ABEVERLEY Dancer2::Plugin::Auth::Extensible. 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-2026-15689/ (Markdown: https://insights.sbomify.com/CVE-2026-15689/index.md)","id":"CVE-2026-15689","markdown":"https://insights.sbomify.com/CVE-2026-15689/index.md","name":"CVE-2026-15689","record":{"aliases":["GHSA-gmj3-5xfg-q3qg","openSUSE-SU-2026:11564-1"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl authentication plugin","requires_auth":"none","summary":"Attackers can poison password reset links via Host header manipulation to steal reset codes and take over user accounts in Dancer2 applications.","user_interaction":"not_required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-640","name":"Weak Password Recovery Mechanism for Forgotten Password"}],"description":"Dancer2::Plugin::Auth::Extensible versions through 0.713 for Perl allow password reset link poisoning via the request Host header in _default_email_password_reset and _default_welcome_send.\n\nBoth default emails emit a link of the form `$base/login/$code`, whose authority comes from the request Host header, or from X-Forwarded-Host under behind_proxy (obtained from Dancer2's request-\u003ebase function).
