### 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

A vulnerability was discovered in Keycloak's Admin UI extension that allows certain administrative users to bypass security restrictions. When Fine-Grained Admin Permissions (FGAPv2) are enabled, an administrator who should only be able to search for users (but not view their full details) can use a specific "brute-force-user" endpoint to access a user's full profile. This includes sensitive information and security metadata. The issue occurs because the system fails to check if the administrato

A flaw was found in Keycloak. A highly privileged user with `manage-clients` permission can exploit this vulnerability by injecting a hardcoded role mapper into any client. This action allows the user to bypass existing scope restrictions and inject the `realm-admin` role into generated tokens, resulting in privilege escalation and full administrative access to the realm.

In SurrealDB, records can be connected as a graph: a `RELATE` statement creates an edge record between two node records. If either endpoint node is deleted, SurrealDB automatically removes the edge row to keep the graph consistent. A user with permission to delete a node could also delete the edges connected to that node, even when the edge table's `PERMISSIONS FOR delete` clause should have stopped them. The automatic edge removal (`Document::purge_edges`) ran with permissions disabled (`opt.

When a user configures `ALGORITHM ES512` for any JWT access method (`DEFINE ACCESS ... TYPE JWT ALGORITHM ES512`), SurrealDB silently substitutes ES384 at all four internal algorithm conversion points. This occurs because the underlying `jsonwebtoken` crate (v10.x) does not include an ES512 algorithm variant, so the mapping defaults to ES384 without raising an error, warning, or log message. Users who provide the correct P-521 key type for ES512 will experience authentication handshake failure

A record user could learn the value of a hidden field by counting how many records match a guess. When `DEFINE FIELD ... PERMISSIONS FOR select WHERE ...` hides a field's contents from a caller, and that field is indexed, running `SELECT count() FROM t WHERE hidden_field = "guess" GROUP ALL` returned a count greater than zero whenever a record actually had that value — even though the caller was never allowed to read the field directly. The query planner used an indexed-COUNT shortcut (`Index::

An anonymous caller could create new namespaces and databases on a running SurrealDB instance without holding `DEFINE NAMESPACE` or `DEFINE DATABASE` permission. `USE NS <name>` and `USE DB <name>` automatically create the target when it does not exist. The three places `USE` is handled — the RPC `use` method, `Datastore::process_use`, and the SurrealQL executor — did not check whether the caller was allowed to create the resource. Under default capabilities any session reached this path, inclu

SurrealDB offers `http::*` functions that can access external network endpoints, with the `--allow-net` and `--deny-net` capabilities used to restrict the set of network targets that can be reached. An authenticated user of SurrealDB can bypass a port-scoped `--deny-net <host>:<port>` rule by chaining an HTTP redirect: the initial request goes to an `--allow-net`-permitted hostname, the response's `3xx Location` header points at the denied `host:port`, and the redirect is followed even though th

A record user could read records the table's SELECT permission expression should have hidden, when that expression referenced `$value`, `$before`, `$after`, or `$event`. Binding a chosen value to that name before registering a `LIVE SELECT` caused notifications to evaluate the permission against the attacker's input instead of the real document. ### Impact A record user binds a value to `$value`, `$before`, `$after`, or `$event` (e.g. `LET $value = [$auth.id]`) and registers `LIVE SELECT * FRO

`RELATE` creates an edge record between two existing records, and SurrealDB enforces the `CREATE` permission on the edge table for this operation. When the statement included a `SET id = edge:existing` clause, however, the new edge's id ended up pointing at an record that was already in storage. Rather than failing because the target already existed — which is what a create operation should do — the storage layer silently overwrote the existing edge. A caller with `CREATE` permission could there

SurrealDB lets callers modify records using JSON Patch operations via the `UPDATE … PATCH` statement (and SDK equivalents such as `db.patch()`). One of those operations is `copy`, which duplicates one field's value into another field of the same record. A `PATCH` with an empty `from` — for example, `UPDATE thing:1 PATCH [{ op: 'copy', from: '', path: '/leak' }]` — was treated as "copy the entire record" and duplicated every field, including fields the caller has no permission to read, into the d

The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. In versions from 2.0.0 prior to 2.16.0 and from 3.0.0.Beta1 prior to 3.0.11, ThreadSafeCookieStore stored a cookie under the value of its Domain attribute without verifying that the responding host is allowed to set a cookie for that domain, leading to a cookie tossing / cookie injection issue. A host the client connects to can therefore plant a cookie scoped to a

In Vinyl Cache before 9.0.1 and Varnish Cache before 9.0.3, a deficiency in HTTP/2 request parsing can be exploited to launch a backend request desync attack (request smuggling), which in turn can be used for cache poisoning, authentication bypass, or possibly even information disclosure and manipulation. The attack vector only exists if HTTP/2 support is enabled by setting the feature parameter to contain +http2. HTTP/2 support is disabled by default.

Mermaid is a JavaScript tool that uses Markdown-inspired text to create and modify diagrams and charts. Prior to 10.9.6 and 11.15.0, Mermaid's default configuration allows injecting CSS that applies outside of the Mermaid diagram via the fontFamily, themeCSS, and altFontFamily configuration options. The injected CSS exploits stylis's & (scope reference) handling. :not(&) escapes the #mermaid-xxx automatic scoping, applying styles to all page elements. Global at-rules (@font-face, @keyframes, @c

Dell Device Management Agent, versions prior to DDMA 26.05, contain an Improper Link Resolution Before File Access ('Link Following’) vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of Privileges.
