React Router is a router for React. In versions 7.7.0 through 7.13.1, when using React Router's unstable React Server Components (RSC) APIs, there is a potential client-side Cross-Site Scripting (XSS) vulnerability in the RSC redirect handling if redirects come from untrusted sources. This does not impact applications that are not using the unstable RSC APIs in React Router. This is patched in version 7.13.2.

CVE-2026-626497.5 HIG—
——0A vulnerability has been identified in Reyrolle 7SR5 (All versions < V2.70). The web server does not properly limit or manage system resources when processing a high volume of concurrent HTTP requests. This could allow an unauthenticated remote attacker to cause the entire device to crash and reboot, resulting in a denial-of-service condition.8hCVE-2026-488887.5 HIG—
——0Allocation of Resources Without Limits or Throttling vulnerability in Automattic WooCommerce allows HTTP DoS.
This issue affects WooCommerce: from n/a before 11.1.0.4hCVE-2026-865135.3 MED—
——0A security flaw has been discovered in java-json-tools jackson-coreutils 2.0. This vulnerability affects the function TreePointer.tokensFromInput of the file src/main/java/com/github/fge/jackson/jsonpointer/TreePointer.java of the component JSON Pointer parser. The manipulation results in allocation of resources. The attack can be executed remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.4hCVE-2026-75808——
——0Allocation of Resources Without Limits or Throttling in ASUS Armoury Crate allows a local user to cause a denial-of-service condition through system memory exhaustion by bypassing driver authentication and allocating an unrestricted amount of memory.Refer to the '
Security Update for Armoury Crate App ' section on the ASUS Security Advisory for more information.14hCVE-2026-82753——
——0Allocation of Resources Without Limits or Throttling vulnerability in ash-project ash_authentication_oauth2_server allows an unauthenticated attacker to exhaust database storage and memory.
The /authorize endpoint is unauthenticated by design. With Client ID Metadata Documents enabled, resolve_client/3 in AshAuthentication.Oauth2Server.CIMD fetches the document for each new URL-shaped client_id and upserts a client row, with no cap on the number of rows, no expiry or garbage collection, and no length bound on the fetched fields; the document was also placed in CIMD.Cache before validation, so even rejected documents held cache memory until their TTL. An attacker serving valid documents at many distinct URLs creates one permanent client row per URL, each able to carry multi-megabyte strings, growing storage and memory without bound.
This issue affects ash_authentication_oauth2_server: from 0.3.0 before 0.3.1.18hCVE-2026-86452——
——0Affected versions of MISP permit unauthenticated or weakly constrained request paths to perform persistent work without adequate input bounds or rate limiting.
The users/forgot password-reset endpoint accepted an attacker-controlled email value without first imposing a reasonable length bound or validating its format. That value was then used to create an audit log entry and queue a password-reset job, causing the supplied value to be persisted more than once per request. The commit explicitly states that an unbounded unauthenticated request field was stored twice per call with no throttle.
The fix adds:
*
a maximum email input length of 1024 bytes;
*
email-format validation before persistent work;
*
a per-source pre-authentication request budget;
*
HTTP 429 responses when that budget is exceeded;
*
a 15-minute cooldown for API-access request emails;
*
POST-only handling and CSRF protection for the API-access request endpoint.
The new flood filter is specifically intended to limit persistent storage costs from anonymous requests such as password resets, registrations, and failed REST authentication attempts.
