Rekor has an OOM Condition due to Unbounded gzip Decompression in Alpine APK Parsing Logic

The Package.Unmarshal() function in pkg/types/alpine/apk.go decompresses the signature and control gzip members of an APK file into in-memory buffers without bounding the total decompressed size. The existing max_apk_metadata_size check (default 1MB) is only applied to individual tar entry header sizes after decompression completes, so it does not prevent a decompression bomb from consuming unbounded heap memory. An attacker can craft a gzip stream that compresses at a ~1000:1 ratio (e.g., …

opentelemetry_sdk has unbounded memory allocation in W3C Baggage propagation

BaggagePropagator::extract_with_context in opentelemetry_sdk did not enforce the W3C Baggage size limits before parsing an inbound baggage header. A large attacker-controlled header could cause unnecessary CPU work and short-lived heap allocations while parsing entries that would later be discarded by the SDK's baggage storage limits. The SDK now applies limits aligned with the W3C Baggage limits: 64 list-members 8192 bytes total

OpenAM: Unauthenticated Authentication Bypass via RADIUS Spoofing

Description An Improper Verification of Cryptographic Signature (CWE-347) issue in OpenAM's RADIUS authentication module allows an unauthenticated network attacker to spoof an Access-Accept response and obtain an OpenAM session for any RADIUS username, without knowing the configured shared secret. This affects OpenAM Community Edition through version 16.0.6 and was patched in version 16.1.1. The RADIUS client opens an unconnected datagram socket and treats the first UDP datagram delivered to its …

OpenAM has Unsafe Java Deserialization via SNS

Description A Deserialization of Untrusted Data (CWE-502) issue exists in OpenAM's Push Notification SNS callback resource. The REST route that handles SNS push messages is mounted with anonymous access and, when a supplied message identifier has expired from the in-memory dispatcher, falls back to a CTS-stored predicate blob whose top-level keys are treated as Java class names and passed to Class.forName(…) before attacker-controlled JSON is deserialized via Jackson. This impacts …

OpenAM Arbitrary OAuth Token Minting via Push Registration

Description An Authorization Bypass Through User-Controlled Key (CWE-639) exists in OpenAM's stateful OAuth2 token-read path. Under certain conditions, this may allow an attacker to forge OAuth2 bearer tokens and OIDC ID tokens with arbitrary subject, client, realm, and scope. This affects OpenAM Community Edition through version 16.0.6. The OAuth2 token-read path reads caller-supplied token identifiers from the shared Core Token Store (CTS) without placing them in an OAuth-only namespace and …

nextflow auth login command has incorrect default permissions

nextflow auth login persists Seqera Platform OIDC tokens to ${NXF_HOME:-~/.nextflow}/seqera-auth.config. The file is created via Java NIO without specifying file permissions, so under the default umask 022 it lands at mode 0644 (world-readable). On a multi-user POSIX host — typically an HPC login node, shared workstation, or jump host — any local user able to traverse the victim's home directory can read the file and obtain a valid Platform bearer …

MessagePack-CSharp: Unity unsafe blit formatter allocates from unbounded byte length

UnsafeBlitFormatterBase<T>.Deserialize reads an attacker-controlled byteLength from an extension payload and allocates an array based on that value before validating it against the extension header length or remaining payload bytes. The outer extension header is bounded by available input, but that bound is not used to constrain the inner byteLength before allocation. A very small payload can therefore request a very large T[] allocation.

Two LiteLLM versions published containing credential harvesting malware

After an API Token exposure from an exploited trivy dependency, two new releases of litellm were uploaded to PyPI containing automatically activated malware, harvesting sensitive credentials and files, and exfiltrating to a remote API. Anyone who has installed and run the project should assume any credentials available to litellm environment may have been exposed, and revoke/rotate thema ccordingly.
