CVE-2026-34388 (GCVE-0-2026-34388)

Vulnerability from cvelistv5 – Published: 2026-03-27 19:13 – Updated: 2026-03-31 13:44

Title
Fleet vulnerable to Denial of Service via unhandled gRPC log type in launcher endpoint
Summary
Fleet is open source device management software. Prior to 4.81.0, a denial-of-service vulnerability in Fleet's gRPC Launcher endpoint allows an authenticated host to crash the entire Fleet server process by sending an unexpected log type value. The server terminates immediately, disrupting all connected hosts, MDM enrollments, and API consumers. Version 4.81.0 patches the issue.

CVE-2026-44893 (GCVE-0-2026-44893)

Title
Netty: HAProxy SSL TLV parsing leaks retained slice on invalid TLV length
Summary
Netty is a network application framework for development of protocol servers and clients. In netty-codec-haproxy prior to versions 4.1.135.Final and 4.2.15.Final, when decoding a PP2_TYPE_SSL TLV, HAProxyMessage.readNextTLV() first calls `header.retainedSlice(header.readerIndex(), length)` and only then reads the 1-byte client field and 4-byte verify field. If the attacker sets the TLV length below 5, the subsequent readByte/readInt throws IndexOutOfBoundsException. HAProxyMessageDecoder only catches HAProxyProtocolException around this call, so the IOOBE propagates and the retained slice on the pooled cumulation buffer is never released. Versions 4.1.135.Final and 4.2.15.Final patch the issue.

CVE-2026-56338 (GCVE-0-2026-56338)

Vulnerability from cvelistv5 – Published: 2026-06-24 11:53 – Updated: 2026-06-24 14:59

Title
Capgo - Denial of Service in 2FA Email Verification via /auth/v1/otp Endpoint
Summary
Capgo before 12.128.2 contains a denial of service vulnerability in the /auth/v1/otp endpoint that prevents email verification for two-factor authentication due to captcha validation failures. Authenticated users cannot complete 2FA enrollment as the backend consistently returns HTTP 500 errors with captcha verification process failed messages, blocking access to security controls.
