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-2024-22192 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- ursa (crates.io): affected all versions up to 0.3.7; no fix listed\n- ursa (crates.io): affected all versions up to 0.3.7; no fix listed\n- anoncreds-clsignatures (crates.io): affected all versions; fixed in 0.1.0\n- anoncreds-clsignatures (crates.io): affected all versions; fixed in 0.1.0\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-2024-22192/ (Markdown: https://insights.sbomify.com/CVE-2024-22192/index.md)","id":"CVE-2024-22192","markdown":"https://insights.sbomify.com/CVE-2024-22192/index.md","name":"CVE-2024-22192","record":{"aliases":["GHSA-6698-mhxx-r84g"],"analysis":{"component_type":"library","fix_type":"end_of_life","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Blockchain cryptographic library","requires_auth":"none","summary":"A flaw in Ursa's revocation scheme allows malicious verifiers to generate unique identifiers for holders, compromising privacy in verifiable presentations.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"ursa","vendor":"hyperledger"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"Ursa is a cryptographic library for use with blockchains. The revocation scheme that is part of the Ursa CL-Signatures implementations has a flaw that could impact the privacy guarantees defined by the AnonCreds verifiable credential model.

The impact of the flaw is that a malicious verifier may be able to determine a unique identifier for a holder presenting a Non-Revocation proof.
