An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-16615 in the wild and no public exploit code.\n\nAffected product: GNOME Red Hat Enterprise Linux 10. 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-2026-16615/ (Markdown: https://insights.sbomify.com/CVE-2026-16615/index.md)","id":"CVE-2026-16615","markdown":"https://insights.sbomify.com/CVE-2026-16615/index.md","name":"CVE-2026-16615","record":{"aliases":["ALSA-2026:47085","AZL-93303","DEBIAN-CVE-2026-16615","GHSA-223h-642r-2f6v","MGASA-2026-0436","OESA-2026-3974","OESA-2026-3975","OESA-2026-3976","RHSA-2026:47085","RHSA-2026:62222","RLSA-2026:47085","SUSE-SU-2026:23564-1","SUSE-SU-2026:3795-1","SUSE-SU-2026:3796-1","SUSE-SU-2026:3834-1","UBUNTU-CVE-2026-16615","openSUSE-SU-2026:11477-1","openSUSE-SU-2026:21563-1","openSUSE-SU-2026:21694-1"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["security_bypass","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"OAuth library","requires_auth":"none","summary":"Weak random number generation in librest's PKCE implementation allows attackers to predict code verifiers and bypass OAuth protections.","user_interaction":"required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-338","name":"Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)"}],"description":"A flaw was found in librest.
