CVE-2026-82439

Unknown No fix identified

Not yet in NVD's feed. The description, CVSS and CWE below come from the CVE Numbering Authority's own record, not from NVD analyst review. NVD's own page for this identifier may not exist yet.

Published yesterday. NVD backfills CPE data for days or weeks after publication, and OSV and the exploit indexes lag too. Scope and status here may change.

Description

Description The DRPC server kept a map from function name to request queue and created an entry the first time a function name was seen. No code path ever removed an entry: request cleanup removed the request from its queue, and the shutdown path drained queues, but the queue object and its map entry remained for the life of the process. Function names come from the client and are not constrained to functions any topology has registered, so the number of retained entries is bounded only by the number of distinct names an attacker chooses to send, and each retained entry holds the name itself. drpc.authorizer is unset by default, so no credentials are required to reach the endpoint. The retained state is permanent rather than a transient load spike, so the effect accumulates until the DRPC server exhausts its heap. Mitigation Upgrade to 3.1.0, where a function's queue is removed once nothing is waiting in it. Users who cannot upgrade immediately should configure drpc.authorizer so that only trusted principals can reach the DRPC endpoints, and should ensure the DRPC ports are not reachable from untrusted networks.

CWE-770

Exploitation Status

No public exploit

Nothing published shows this CVE being exploited, which is not the same as ruling it out.

  • CISA Vulnrichment no assessment published
  • Indexed PoC none indexed
  • EPSS not scored

Waratek Defense Posture

No fix identified

In RASP's scope, but nothing published names a fix and nothing published shows an exploit. Neither of the two things VRT can act on exists, which is a claim about the available evidence, not about the vulnerability.

  • Protection none
  • Action not-needed
  • Review automated upstream-data
  • Record active
Decided by no-exploit : With no fix path, a public exploit, or a CISA record of one
Finding Resolved from QUEUED-FOR-REVIEW: this CVE affects a known product, but nothing published names a fix and nothing published shows an exploit. That is a statement about the evidence, not about the defect — it does not mean the vulnerability is unimportant or unreachable, only that neither of the two things VRT can act on exists.
