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-2026-9733 in the wild and no public exploit code.\n\nAffected product: HAYAJO Mojolicious::Plugin::Web::Auth::OAuth2. 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-2026-9733/ (Markdown: https://insights.sbomify.com/CVE-2026-9733/index.md)","id":"CVE-2026-9733","markdown":"https://insights.sbomify.com/CVE-2026-9733/index.md","name":"CVE-2026-9733","record":{"aliases":["GHSA-rq65-66g5-5pg2"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl OAuth2 plugin","requires_auth":"none","summary":"An attacker can hijack user sessions via CSRF due to predictable OAuth2 state parameters generated from low-entropy sources.","user_interaction":"not_required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-340","name":"Generation of Predictable Numbers or Identifiers"},{"id":"CWE-338","name":"Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)"}],"description":"Mojolicious::Plugin::Web::Auth::OAuth2 versions through 0.17 for Perl have an insecure default state parameter.\n\nWhen no state generator is specified in the constructor, the module defaults to using a SHA-1 hash of predictable and low-entropy sources, including the epoch time (which is leaked via the HTTP Date header) and a call to Perl's built-in rand function.\n\nA predictable state allows an attacker to hijack another user's session through cross site request forgery (CSRF).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Mojolicious::Plugin::Web::Auth::OAuth2 versions through 0.17 for Perl have an insecure default state parameter","id":"CVE-2026-9733","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"csrf","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"W3SC Elementor to Zoho CRM \u003c= 2.2.0 - Cross-Site Request Forgery to Settings Update","id":"CVE-2026-9734"},"packages":[],"prev":{"headline":"EmergencyWP \u003c= 1.4.2 - Cross-Site Request Forgery to Plugin Settings Update","id":"CVE-2026-9732"},"products":["Mojolicious::Plugin::Web::Auth::OAuth2"],"published":"2026-06-23","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-06-23","vendors":["HAYAJO"]},"summary":"An attacker can hijack user sessions via CSRF due to predictable OAuth2 state parameters generated from low-entropy sources.","url":"https://insights.sbomify.com/CVE-2026-9733/"}
