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-2025-40905 in the wild and no public exploit code.\n\nAffected product: DBOOK WWW::OAuth. 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-2025-40905/ (Markdown: https://insights.sbomify.com/CVE-2025-40905/index.md)","id":"CVE-2025-40905","markdown":"https://insights.sbomify.com/CVE-2025-40905/index.md","name":"CVE-2025-40905","record":{"aliases":["DEBIAN-CVE-2025-40905","GHSA-869w-qxf5-5q39","UBUNTU-CVE-2025-40905"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl OAuth library","requires_auth":"none","summary":"The Perl WWW::OAuth library uses insecure random number generation for cryptographic operations, potentially allowing attackers to bypass security controls.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[{"product":"www\\","vendor":"dbook"}],"cvss":{"score":7.3,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-338","name":"Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)"}],"description":"WWW::OAuth 1.000 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"WWW::OAuth 1.000 and earlier for Perl uses insecure rand() function for cryptographic functions","id":"CVE-2025-40905","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"BSON::XS versions 0.8.4 and earlier for Perl includes a bundled libbson 1.1.7, which has several vulnerabilities","id":"CVE-2025-40906"},"packages":[],"prev":{"headline":"HTML injection in Smart Polling in Guardian/CMC before 26.1.0","id":"CVE-2025-40904"},"products":["WWW::OAuth"],"published":"2026-02-12","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"2026-02-17","vendors":["DBOOK"]},"summary":"The Perl WWW::OAuth library uses insecure random number generation for cryptographic operations, potentially allowing attackers to bypass security controls.","url":"https://insights.sbomify.com/CVE-2025-40905/"}
