Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-47241 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- net-imap (RubyGems): affected all versions; fixed in 0.5.15\n- net-imap (RubyGems): affected all versions; fixed in 0.5.15\n- net-imap (RubyGems): affected from 0.6.0; fixed in 0.6.4.1\n- net-imap (RubyGems): affected from 0.6.0; fixed in 0.6.4.1\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-2026-47241/ (Markdown: https://insights.sbomify.com/CVE-2026-47241/index.md)","id":"CVE-2026-47241","markdown":"https://insights.sbomify.com/CVE-2026-47241/index.md","name":"CVE-2026-47241","record":{"aliases":["ALPINE-CVE-2026-47241","BELL-CVE-2026-47241","CLEANSTART-2026-HQ73324","CLEANSTART-2026-NQ87624","DEBIAN-CVE-2026-47241","ECHO-bf99-96ee-af6b","GHSA-c4fp-cxrr-mj66","MINI-22v4-4354-vvmh","MINI-2528-pgg6-h4wp","MINI-2vf5-v3cj-mwcc","MINI-2xhf-q398-q93x","MINI-35f4-gw8q-p3rm","MINI-5pc8-mvx4-vvv3","MINI-7j24-3v7w-qhmm","MINI-7px6-fx4c-7f32","MINI-g4vq-x5w2-66p9","MINI-hww9-r2jp-9c2r","MINI-jq65-38wf-qm57","MINI-r6pm-ccqm-647f","MINI-v2g8-5phm-c9q7","MINI-w8mm-h7mc-m5c5","MINI-xw8g-7x5f-5wrq","UBUNTU-CVE-2026-47241"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby IMAP client library","requires_auth":"low_privilege","summary":"Attackers can cause a denial of service in Ruby's Net::IMAP library by sending crafted raw arguments that block command execution.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":2.1,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:P/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-186","name":"Overly Restrictive Regular Expression"},{"id":"CWE-182","name":"Collapse of Data into Unsafe Value"},{"id":"CWE-162","name":"Improper Neutralization of Trailing Special Elements"}],"description":"Net::IMAP implements Internet Message Access Protocol (IMAP) client functionality in Ruby. Prior to 0.6.5 and 0.5.15, several Net::IMAP commands accept a raw string argument which is only validated to prevent CRLF injection and then sent verbatim. If this string is derived from user-controlled input, an attacker can force the next command to be absorbed as a continuation of the first command. This will cause the first command to eventually fail, but also prevents it from returning until another command is sent (from another thread). That other command will not return until the connection is closed. This vulnerability is fixed in 0.6.5 and 0.5.15.","ecosystems":["RubyGems"],"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":"Net::IMAP: Denial of Service via incomplete raw argument validation","id":"CVE-2026-47241","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":4,"n_references":1,"next":{"headline":"Net::IMAP: Command Injection via ID command argument","id":"CVE-2026-47242"},"packages":[{"ecosystem":"RubyGems","fixed":["0.5.15"],"introduced":["0"],"last_affected":[],"package":"net-imap","purl":null,"source":"GHSA-c4fp-cxrr-mj66"},{"ecosystem":"RubyGems","fixed":["0.5.15"],"introduced":["0"],"last_affected":[],"package":"net-imap","purl":"pkg:gem/net-imap","source":"GHSA-c4fp-cxrr-mj66"},{"ecosystem":"RubyGems","fixed":["0.6.4.1"],"introduced":["0.6.0"],"last_affected":[],"package":"net-imap","purl":null,"source":"GHSA-c4fp-cxrr-mj66"},{"ecosystem":"RubyGems","fixed":["0.6.4.1"],"introduced":["0.6.0"],"last_affected":[],"package":"net-imap","purl":"pkg:gem/net-imap","source":"GHSA-c4fp-cxrr-mj66"}],"prev":{"headline":"Net::IMAP: Command Injection via non-synchronizing literal in \"raw\" argument","id":"CVE-2026-47240"},"products":["net-imap"],"published":"2026-06-22","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2026-06-23","vendors":["ruby"]},"summary":"Attackers can cause a denial of service in Ruby's Net::IMAP library by sending crafted raw arguments that block command execution.","url":"https://insights.sbomify.com/CVE-2026-47241/"}
