CVE-2026-42811 Apache Polaris: could broaden vended GCS credentials through unescaped identifier content in access-boundary CEL conditions
In plain terms, Apache Polaris is supposed to issue short-lived GCS credentials
that
only work for one table's files, but a crafted namespace or table name can
cause those credentials to work across the configured bucket instead.


Apache Polaris builds Google Cloud Storage downscoped credentials by creating a
Credential Access Boundary (CAB) with CEL conditions that are intended to
restrict access to the requested table's storage path.



The relevant CEL string is built from the bucket name and the table path.
That
table path is derived from namespace and table identifiers. In current code,
that path appears to be inserted into the CEL expression without escaping.



As a result, a namespace or table identifier containing a single quote and
other URI-safe CEL fragments can break out of the intended quoted string and
change the meaning of the CEL condition.



In private testing against Polaris 1.4.0 on real Google Cloud Storage, it was confirmed that Polaris accepted a crafted identifier and returned delegated
GCS
credentials whose CEL path restriction had effectively collapsed.


Those delegated credentials could then:


- list another table's object prefix;

- read another table's metadata control file (Iceberg metadata JSON);

- create and delete an object under another table's object prefix;

- and also list, read, create, and delete objects under an unrelated
external
prefix in the same bucket that was not part of any table path.



That last point is important. The issue is not limited to "another table".
In
the confirmed setup, once Apache Polaris returned credentials for the crafted
table,
the path restriction inside the configured bucket was effectively gone.

The practical effect is that temporary credentials for one crafted table
can be
broader than the table Polaris was asked to authorize, and can become
effectively bucket-wide within the configured bucket.



The current GCS testing used a Polaris principal with broad catalog
privileges for setup. A separate least-privilege Polaris RBAC variant
has not yet been tested on GCS. However, the storage-credential
broadening behavior itself has been confirmed on GCS.

CVE-2026-42841 Grav: Stored XSS via Markdown media attribute() action in Grav CMS
Grav is a file-based Web platform. Prior to 2.0.0-beta.2, an authenticated user with page editing permissions can inject an executable JavaScript event-handler attribute into rendered image HTML through Grav's Markdown media action syntax. The issue is caused by Markdown image query parameters being converted into callable media actions. The public attribute() media method can be reached this way, allowing an editor to set an arbitrary HTML attribute name and value on the generated image element. This vulnerability is fixed in 2.0.0-beta.2.

Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site's content, media, configuration, users, and system management. Prior to 1.0.0-beta.15, an insecure direct object reference and logic flaw in the Grav API plugin (UsersController::update) allows any authenticated user with basic API access (api.access) to modify their own permission configuration. An attacker can exploit this to escalate their privileges to Super Administrator (admin.super and api.super), leading to full system compromise and potential RCE. This vulnerability is fixed in 1.0.0-beta.15.

The form plugin for Grav adds the ability to create and use forms. Prior to 9.1.0 , there is an unauthenticated page-content overwrite via file upload (GHSA-w4rc-p66m-x6qq). Public form uploads now strip path components from the POST-supplied filename and hard-block page-content extensions (`md`, `yaml`, `yml`, `json`, `twig`, `ini`) regardless of the configurable dangerous-extensions list. A permissive `accept` policy combined with the default `destination: self@` could otherwise let an attacker overwrite the page's own `.md` and pivot to super-admin via a `process: save` action. This vulnerability is fixed in 9.1.0.

Prior to 5.5.3 - #122, there is a critical SQL Injection (SQLi) vulnerability in ClipBucket, exploitable through the type parameter on the authenticated admin endpoint admin_area/action_logs.php. The endpoint admin_area/action_logs.php reads $_GET['type'], stores it in $result_array['type'], and forwards it into fetch_action_logs(), where the value is concatenated directly into a SQL WHERE condition on action_type without parameterization. This allows UNION-based SQL injection and direct data exfiltration from the database. This vulnerability is fixed in 5.5.3 - #122.

Open edX Platform enables the authoring and delivery of online learning at any scale. The sync_provider_data endpoint in SAMLProviderDataViewSet allows authenticated Enterprise Admin users to supply an arbitrary URL via the metadata_url POST parameter. This URL is passed directly to requests.get() in fetch_metadata_xml() without any URL validation, IP filtering, or scheme enforcement. An attacker with Enterprise Admin privileges can force the server to make HTTP requests to internal network services, cloud metadata endpoints (e.g., AWS 169.254.169.254), or other attacker-controlled destinations. This vulnerability is fixed by commit 6fda1f120ff5a590d120ae1180185525f399c6d0 and 70a56246dd9c9df57c596e64bdd8a11b1d9da054.
