Denial of service in ISC BIND 9 resolvers (9.20.0-9.20.24, 9.21.0-9.21.23, and 9.20.9-S1-9.20.24-S1) lets remote unauthenticated attackers exhaust CPU by luring a validating resolver to query an authoritative zone that returns many valid-but-superfluous RRSIG records, which BIND always validates even when unnecessary. The CVSS 7.5 vector (AV:N/AC:L/PR:N/UI:N/A:H) reflects an availability-only impact with no confidentiality or integrity loss. There is no public exploit identified at time of analysis and it is not in CISA KEV, but ISC has released fixed builds (9.20.26 and 9.21.24).
Amplified resource exhaustion in ISC BIND 9 resolvers enables remote unauthenticated attackers to cause disproportionate resource consumption by directing a victim resolver to query a specially crafted authoritative DNS zone. All major BIND 9 resolver branches are affected, spanning versions 9.11.x through 9.21.x including BIND 9 Supported (S1) variants, representing a broad deployment footprint across enterprise and ISP resolver infrastructure. No public exploit has been identified at time of analysis and the vulnerability is not listed in CISA KEV; ISC has released patched versions.
Resource exhaustion in OpenClaw before 2026.3.31 allows remote unauthenticated attackers to crash servers by sending malicious Microsoft Teams webhook payloads. The application parses request bodies before performing JWT validation, enabling attackers to bypass authentication and trigger denial-of-service conditions. A vendor patch is available via GitHub commit 3834d47, with no evidence of active exploitation (not in CISA KEV) and no public POC identified at time of analysis.
OpenClaw before version 2026.3.31 performs Discord audio preflight transcription without validating member authorization, allowing unauthenticated remote attackers to trigger resource-intensive audio processing and cause denial of service through resource exhaustion.
OpenClaw before version 2026.3.31 allows unauthenticated remote attackers to trigger resource-intensive audio transcription processing via Telegram without proper authorization, enabling denial-of-service through billing or infrastructure exhaustion. The vulnerability stems from insufficient allowlist enforcement that permits unauthorized group senders to initiate preflight transcription operations before authentication is validated, and no public exploit code has been identified at the time of analysis.
In Eclipse Californium version 2.0.0 to 2.7.2 and 3.0.0-3.5.0 a DTLS resumption handshake falls back to a DTLS full handshake on a parameter mismatch without using a HelloVerifyRequest. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
On SRX Series devices, a vulnerability in the key-management-daemon (kmd) daemon of Juniper Networks Junos OS allows an attacker to spoof packets targeted to IPSec peers before a security association. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
