GHSA-MQXV-9RM6-W8QC Ech0: ParseAcceptLanguage `_` separator bypass enables ~70x CPU amplification via Accept-Language header in i18n.Middleware

Summary Ech0's i18n middleware runs on every HTTP request and constructs a fresh goi18n.Localizer from the raw Accept-Language header without imposing any size or shape filter. goi18n.NewLocalizer calls golang.org/x/text/language.ParseAcceptLanguage on the value internally. The underlying parser...

GHSA-443G-GWGP-49X4 zebrad vulnerable to getblocks/getheaders locator CPU amplification via uncapped vector length

Am I affected You are affected if: 1. You run zebrad up to and including v4.4.1. 2. Your node accepts inbound P2P connections. Summary The readgetblocks and readgetheaders codec paths accepted block locator vectors up to approximately 65,535 entries the generic TrustedPreallocate ceiling derived...

SUSE CVE-2026-29181

OpenTelemetry-Go is the Go implementation of OpenTelemetry. From 1.36.0 to 1.40.0, multi-value baggage: header extraction parses each header field-value independently and aggregates members across values. This allows an attacker to amplify cpu and allocations by sending many baggage: header lines...

389-ds-base: 389-ds-base: unbounded LDAP controls count in get_ldapmessage_controls_ext() causes CPU and heap amplification (remote DoS)

A flaw was found in 389-ds-base. The getldapmessagecontrolsext function in the LDAP server does not enforce an upper bound on the number of controls per LDAP message. A remote, unauthenticated attacker can send a specially crafted LDAP request containing hundreds of thousands of minimal controls...

PBES2-HS*+A*KW unwrap accepts an unbounded p2c iteration count, enabling CPU-amplification denial of service

Impact When a JWE uses a password-based key-encryption algorithm PBES2-HS256+A128KW, PBES2-HS384+A192KW, PBES2-HS512+A256KW, PBES2AESKW::unwrapKey reads the p2c PBKDF2 iteration count parameter directly from the attacker-controlled JOSE header and passes it to hashpbkdf2 with no upper bound. The...

Klever-Go KVM: Hash-array amplification in P2P resolver request handling

Summary A connected peer can send a compressed RequestDataTypeHashArrayType direct request that is only 442 bytes on the wire but expands into 200000 decoded hash entries inside the resolver path. On klever-go v1.7.17, this allows remote memory and CPU amplification against nodes that accept P2P...

CVE-2026-29181

OpenTelemetry-Go (Go implementation) has a vulnerability in multi-value baggage header extraction: from versions 1.36.0 through 1.40.0, parsing each header field-value independently causes aggregation of members across values, enabling an attacker to trigger excessive CPU and memory allocations a...
