CVE-2026-82439Not 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
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
No public exploit
Nothing published shows this CVE being exploited, which is not the same as ruling it out.
CVSS E:U
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.
| 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. |
