The file content store in `oras-go` attempts to confine writes to `workingDir` when `AllowPathTraversalOnWrite=false`, but the guard is lexical and does not account for symlink traversal. If `workingDir` contains a symlink path component and an attacker-controlled blob title (via `ocispec.AnnotationTitle`) targets a path under that symlink, `pushFile()` can create a file outside `workingDir`. ## relevant links - repository: https://github.com/oras-project/oras-go - commit: 03243809936cce826494

The massive FortiBleed credential theft campaign has been linked to the INC and Lynx ransomware operations, suggesting the stolen Fortinet credentials were intended to fuel future network intrusions. [...]

## Summary oras-go follows a registry-controlled `Location` header during the monolithic blob upload flow and reuses the `Authorization` header from the initial `POST` request for the subsequent `PUT` request. If a malicious registry returns a cross-host `Location`, oras-go can send the caller's credentials to an attacker-controlled endpoint. ## Affected Versions tested: v2.6.0 (commit 03243809936cce826494b5506f724c6dc11115b1, as-of 2026-01-24) range: unknown; likely affects earlier v2.x rele

### Description A flaw was found in Keycloak's Fine-Grained Admin Permissions (FGAPv2) feature. An administrator with limited client management permissions can exploit this vulnerability to assign any realm role, including highly privileged roles, to a client's scope mapping. This bypasses intended security controls, allowing the injected role to be projected into a user's authentication token when they access the modified client. This could lead to unauthorized privilege escalation within the K

Heap-based buffer overflow in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally.

Improper neutralization of input during web page generation ('cross-site scripting') in Microsoft Entra ID allows an authorized attacker to perform spoofing over a network.

## Summary oras-go's `auth.Client` follows the `realm` URL from a registry's `WWW-Authenticate: Bearer` challenge without validating its scheme or host. The `realm` field is server-controlled by design in the OCI/distribution spec — registries legitimately point token requests at a separate auth endpoint (e.g. Docker Hub's `registry-1.docker.io` -> `auth.docker.io`), so cross-host realms on public DNS names are not in themselves a vulnerability. Two specific patterns, however, are never legitim

### Summary The fix for GHSA-fpxj-m5q8-fphw (CVE-2026-45710, "Mailpit: Set a default 50MB p/m limit to prevent DoS via unlimited SMTP DATA and /api/v1/send body sizes") wrapped only `POST /api/v1/send` with `http.MaxBytesReader`. The four other Mailpit JSON-body API endpoints `PUT /api/v1/messages` (SetReadStatus), `DELETE /api/v1/messages` (DeleteMessages), `PUT /api/v1/tags` (SetMessageTags), and `POST /api/v1/message/{id}/release` (ReleaseMessage) still call `json.NewDecoder(r.Body)` direc

### Summary `dist/clients/core/params.ts` in `@hey-api/openapi-ts` ships a runtime template that is copied verbatim into every generated SDK as `params.gen.ts`. When a caller passes an object argument containing an unknown key starting with a slot prefix (`$body_`, `$headers_`, `$path_`, `$query_`), the function strips the prefix and writes the remainder directly to that slot without validation. The key `"$query___proto__"` causes the returned `params.query` object to have its prototype chain s

### Impact A critical command injection vulnerability has been identified in the Rancher Manager cluster import endpoint `/v3/import/{token}_{clusterId}.yaml` through unsanitized YAML parameters. This endpoint accepts an `authImage` query parameter that is rendered without sanitization into a generated Kubernetes manifest template. By including URL-encoded newlines in the parameter value, an attacker can break out of the `image:` field to inject arbitrary YAML keys and malicious configurations,

Side-channel information leakage in Safe Browsing in Google Chrome on iOS prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to leak cross-origin data via a crafted HTML page. (Chromium security severity: High)

### Impact The QUIC client did not authenticate the server during the TLS 1.3 handshake. The CertificateVerify signature was not checked, the certificate chain was not validated, and the hostname was not compared against the certificate, so `verify` was effectively a no-op on the client. A man-in-the-middle on the network path could present any certificate and impersonate any server, defeating the confidentiality and integrity of the connection. HTTP/3 uses the same client and was equally affec

### Summary `ArchiveUtils.untar(InputStream, Path)` and `ArchiveUtils.unzip(InputStream, Path)` in `land.oras:oras-java-sdk` create symbolic-link entries from an archive without validating the symlink target. A malicious tar (or zip) shipped as an OCI layer blob can place a symlink under the extraction directory whose target points outside that directory, then ship a regular-file entry whose path traverses through that symlink. The subsequent `Files.newOutputStream` call follows the symlink and

Insufficient validation of untrusted input in Chrome for iOS in Google Chrome on iOS prior to 150.0.7871.47 allowed a remote attacker who convinced a user to engage in specific UI gestures to inject arbitrary scripts or HTML (UXSS) via a crafted HTML page. (Chromium security severity: High)

#### Summary Centrifugo's dynamic JWKS endpoint feature can verify a JWT for one allowed issuer using a public key cached from another allowed issuer. The JWKS cache and `singleflight` lookup are keyed only by the JWT header `kid`, not by the resolved JWKS endpoint, issuer, audience, or other trust-domain namespace. In a documented multi-issuer dynamic JWKS configuration, an attacker who can obtain or mint a valid token for issuer/tenant A can authenticate as issuer/tenant B if both JWKS docum

A flaw was found in the Identity Provider (IdP) mapper component of Keycloak, which is used to manage how user information from external services is mapped to Keycloak users. An administrator with limited permissions to manage identity providers can exploit this flaw by creating a "Hardcoded Role" mapper that assigns high-level administrative roles (like realm-admin) to themselves or others. This allows a restricted administrator to bypass security checks and gain full control over the entire re
