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-2026-16634 in the wild and no public exploit code.\n\nAffected product: FELIPE TOML::XS. 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-2026-16634/ (Markdown: https://insights.sbomify.com/CVE-2026-16634/index.md)","id":"CVE-2026-16634","markdown":"https://insights.sbomify.com/CVE-2026-16634/index.md","name":"CVE-2026-16634","record":{"aliases":["GHSA-hr7v-gv37-xpx2"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl TOML library","requires_auth":"none","summary":"Attackers can cause denial of service via stack overflow by submitting deeply nested TOML documents to applications using vulnerable TOML::XS versions.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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-1395","name":"Dependency on Vulnerable Third-Party Component"},{"id":"CWE-1104","name":"Use of Unmaintained Third Party Components"}],"description":"TOML::XS versions before 0.06 for Perl bundle an unsupported and vulnerable version of tomlc99.\n\nThe tomlc99 library is no longer maintained, and has an uncontrolled recursion vulnerability publicly reported in the issue tracker.\n\nAny caller that passes untrusted TOML to from_toml risks a stack overflow from a deeply-nested document.\n\nTOML::XS version 0.06 or later uses the successor tomlc17 library.","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":"TOML::XS versions before 0.06 for Perl bundle an unsupported and vulnerable version of tomlc99","id":"CVE-2026-16634","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"Pronamic Pay \u003c= 10.1.0 - Authenticated (Subscriber+) Privilege Escalation via Gravity Forms 'Update user role' Field","id":"CVE-2026-16635"},"packages":[],"prev":{"headline":"boazsegev facil.io WebSocket Frame websocket_parser.h websocket_on_protocol_error input validation","id":"CVE-2026-16632"},"products":["TOML::XS"],"published":"2026-07-24","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":"2026-07-27","vendors":["FELIPE"]},"summary":"Attackers can cause denial of service via stack overflow by submitting deeply nested TOML documents to applications using vulnerable TOML::XS versions.","url":"https://insights.sbomify.com/CVE-2026-16634/"}
