Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-16782 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- rack (RubyGems): affected all versions; fixed in 1.6.12\n- rack (RubyGems): affected all versions; fixed in 1.6.12\n- rack (RubyGems): affected from 2.0.0; fixed in 2.0.8\n- rack (RubyGems): affected from 2.0.0; fixed in 2.0.8\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-2019-16782/ (Markdown: https://insights.sbomify.com/CVE-2019-16782/index.md)","id":"CVE-2019-16782","markdown":"https://insights.sbomify.com/CVE-2019-16782/index.md","name":"CVE-2019-16782","record":{"aliases":["DEBIAN-CVE-2019-16782","GHSA-hrqr-hxpp-chr3","RHSA-2020:2480","SUSE-SU-2021:1162-1","UBUNTU-CVE-2019-16782"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby web server interface","requires_auth":"low_privilege","summary":"Attackers can hijack sessions via timing attacks on session ID lookups in the Rack library, leading to unauthorized access.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"leap","vendor":"opensuse"},{"product":"rack","vendor":"rack"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-203","name":"Observable Discrepancy"},{"id":"CWE-208","name":"Observable Timing Discrepancy"}],"description":"There's a possible information leak / session hijack vulnerability in Rack (RubyGem rack). This vulnerability is patched in versions 1.6.12 and 2.0.8. Attackers may be able to find and hijack sessions by using timing attacks targeting the session id. Session ids are usually stored and indexed in a database that uses some kind of scheme for speeding up lookups of that session id. By carefully measuring the amount of time it takes to look up a session, an attacker may be able to find a valid session id and hijack the session. The session id itself may be generated randomly, but the way the session is indexed by the backing store does not use a secure comparison.","ecosystems":["Red
