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-2026-49941 in the wild and no public exploit code.\n\nAffected product: RRWO Net::CIDR::Set. 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-2026-49941/ (Markdown: https://insights.sbomify.com/CVE-2026-49941/index.md)","id":"CVE-2026-49941","markdown":"https://insights.sbomify.com/CVE-2026-49941/index.md","name":"CVE-2026-49941","record":{"aliases":["DEBIAN-CVE-2026-49941","GHSA-wvxw-q92g-9ghf","UBUNTU-CVE-2026-49941"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl IP address library","requires_auth":"none","summary":"An attacker can cause a denial of service in Perl applications using Net::CIDR::Set by providing malformed IP addresses that trigger indefinite recursion.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[{"product":"net\\","vendor":"rrwo"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-674","name":"Uncontrolled Recursion"},{"id":"CWE-1287","name":"Improper Validation of Specified Type of Input"}],"description":"Net::CIDR::Set versions through 0.20 for Perl did not validate IP addresses.\n\nThe add method called the _encode method to parse addresses.
