Security readout for executives and security teams

Plain-English summary

CVE-2026-24802 affects briandilley/jsonrpc4j through 1.6.0. The public description points to an infinite loop in NoCloseOutputStream.java, which could reduce availability or reliability when triggered. Severity is medium, and no active exploitation is indicated by the provided sources.

Executive priority

Treat as a moderate availability and reliability risk. Prioritize validation in externally reachable or critical services, but do not assume emergency exploitation pressure without new evidence of active attacks.

Technical view

The CVE describes CWE-835, a loop with an unreachable exit condition, in jsonrpc4j src/main/java/com/googlecode/jsonrpc4j modules, specifically NoCloseOutputStream.java. CVSS 4.0 score is 5.3 with network attack vector, low complexity, no privileges required, and passive user interaction. A GitHub pull request is referenced as a patch source.

Likely exposure

Organizations may be exposed if applications directly or transitively use briandilley/jsonrpc4j versions through 1.6.0. Exposure depends on whether affected jsonrpc4j code paths are reachable in deployed services.

Exploitation context

The sources do not report exploitation in the wild, and the CVE is not marked KEV. Based on CVSS, exploitation is network-reachable and low-complexity, but requires passive user interaction. The practical trigger conditions are not fully described publicly.

Researcher notes

The source bundle has a title mismatch: it says buffer overflow, while the description and CWE indicate an infinite loop. Affected-version data is also sparse. Further confirmation from the upstream PR and release artifacts is needed before asserting a fixed version.

Mitigation direction

  • Inventory applications and dependencies for briandilley/jsonrpc4j through 1.6.0.
  • Review GitHub PR #333 and vendor project guidance for the patch status.
  • Upgrade or patch when a validated fixed release or vendor-supported change is available.
  • Prioritize internet-facing or business-critical services using jsonrpc4j.

Validation and detection

  • Check dependency manifests and SBOMs for jsonrpc4j versions through 1.6.0.
  • Confirm whether affected jsonrpc4j code paths are used in deployed applications.
  • Review runtime logs for unexplained hangs or resource exhaustion in services using jsonrpc4j.
  • Track vendor repository updates and release notes tied to PR #333.
