Stroom trusted the 'signer' field in AWS ALB headers without verification. Attackers can bring their own ALB signatures to log in as anyone, or inject malicious regions into the signer ARN to trigger SSRF against the AWS Metadata Service (IMDS).
A critical authentication bypass and SSRF vulnerability in GCHQ's Stroom data platform allows attackers to spoof AWS Application Load Balancer identities or reach internal AWS metadata services.

Authentication Bypass by Spoofing
CVE-2026-57576 is an application-level Denial of Service (DoS) vulnerability in Plone. It resides in the `plone.app.dexterity` and `plone.app.contenttypes` packages, allowing authenticated users with content creation permissions to submit excessively long metadata attributes. Because these fields are stored without length limits and subsequently processed by indexing and rendering engines, they trigger complete server resource exhaustion and thread starvation.
An uncontrolled resource consumption vulnerability in plone.app.contenttypes allows authenticated users to trigger application-level denial of service via oversized filename metadata in file uploads.
An unauthenticated remote SQL injection vulnerability exists in multiple API list endpoints of ReactPress prior to version 3.7.0. The vulnerability stems from unsafe construction of TypeORM QueryBuilder conditions, where untrusted HTTP query parameter keys are interpolated directly into SQL statements as identifiers without sanitization or validation.
CVE-2026-56669 is a high-severity vulnerability in the Elysia web framework (ElysiaJS) that combines Inefficient Algorithmic Complexity (CWE-407) and an Interpretation Conflict (CWE-436). It allows remote, unauthenticated attackers to cause a complete Denial of Service (DoS) via CPU resource exhaustion using specially crafted multipart or urlencoded payloads.
Prior to version 1.7.20, the default-open WebSocket `/subscribe` endpoint in klever-go was vulnerable to remote resource exhaustion. Unauthenticated, remote attackers could crash validator and node processes by exploiting unbounded frame reads, uncapped concurrent connections, unrestricted memory allocation for subscription address keys, and a permanent memory leak in subscription map tracking on client disconnects.
A critical incorrect authorization vulnerability (CWE-863) exists in the Go implementation of the Klever blockchain protocol (klever-go) prior to version 1.7.20. The vulnerability allows an attacker to completely replace a target account's permission set by manipulating the RecipientAddr parameter in a VM built-in function, leading to total account takeover.
