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-2026-73529 in the wild and no public exploit code.\n\nAffected product: alextselegidis plainpad. 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-2026-73529/ (Markdown: https://insights.sbomify.com/CVE-2026-73529/index.md)","id":"CVE-2026-73529","markdown":"https://insights.sbomify.com/CVE-2026-73529/index.md","name":"CVE-2026-73529","record":{"aliases":["GHSA-9fxw-r4jg-3hq3"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["denial_of_service","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Plainpad web application","requires_auth":"none","summary":"Unauthenticated attackers can exhaust CPU resources and bypass login protections in Plainpad due to missing rate limiting on the session endpoint.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"Plainpad through 1.1.1, fixed in commit d3823fc, contains a missing rate limiting vulnerability that allows unauthenticated attackers to send unbounded login requests to the POST /v1/sessions endpoint due to dead code in App\\Http\\Kernel.php that is never instantiated under the Laravel 11+ skeleton, leaving the API throttle configuration unattached to any route. Attackers can exploit this by sending unlimited credential attempts with no lockout or CAPTCHA enforcement, and additionally trigger CPU exhaustion by forcing repeated bcrypt comparisons on each request.","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":"Plainpad Missing Rate Limiting via POST /v1/sessions","id":"CVE-2026-73529","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Flyto2 Core \u003c 2.28.0 SSRF Guard Bypass via is_private_ip()","id":"CVE-2026-73530"},"packages":[],"prev":{"headline":"Cypht \u003c 2.12.2 XSS via FROM Email Header in Contacts Module","id":"CVE-2026-73524"},"products":["plainpad"],"published":"2026-08-18","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":"partial"},"state":"PUBLISHED","updated":"2026-08-18","vendors":["alextselegidis"]},"summary":"Unauthenticated attackers can exhaust CPU resources and bypass login protections in Plainpad due to missing rate limiting on the session endpoint.","url":"https://insights.sbomify.com/CVE-2026-73529/"}
