HTTP Request Smuggling

Overview Affected versions of this package are vulnerable to HTTP Request Smuggling in the process that merges HTTP/1.1 chunked-body trailer fields into Request.headers. An attacker can inject arbitrary HTTP headers by sending specially crafted trailer fields, potentially bypassing header-based...

GHSA-46Q4-43PH-C6FR blaze: Chunked-body trailer fields promoted into Request.headers in blaze-server (front-end header-sanitization bypass)

Summary blaze-server can merge HTTP/1.1 chunked-body trailer fields into Request.headers. Because trailer fields are attacker-controlled, an unauthenticated remote client can inject arbitrary header names/values e.g. X-Forwarded-For, internal-auth headers that a fronting proxy sanitized from the...

Summary The fix released in jackson-core 2.18.6 and 2.21.1 for GHSA-72hv-8253-57qq Number Length Constraint Bypass in Async Parser, published 2026-02-28 is incomplete. The fix commit b0c428e6 1555 wired validateIntegerLength into a new setIntLength helper and called it at every place where the...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the NonBlockingUtf8JsonParserBase file. An attacker can exhaust system memory by streaming JSON input in small chunks to the asynchronous parser, causing unbounded accumulation of...

CVE-2026-15432

When verifying a mac with a ChunkedMacVerification object, Tink compares the resulting tag with non constant time comparison. This potentially allows an attacker to use timinig information as a side channel in order to get information how many bytes of a given tag match the correct tag. This in...

CVE-2026-15432 Observable Timing Discrepancy in Tink-Java and Tink-Android ChunkedMacVerification

When verifying a mac with a ChunkedMacVerification object, Tink compares the resulting tag with non constant time comparison. This potentially allows an attacker to use timinig information as a side channel in order to get information how many bytes of a given tag match the correct tag. This in...

CVE-2026-15432

The CVE concerns Tink-Java and Tink-Android’s ChunkedMacVerification: during tag verification, the implementation uses a non-constant-time comparison, enabling a timing side-channel that could reveal how many bytes of a given tag match the correct tag. This is described as a potential pathway for...
