Summary
In the ClickHouse connector deployment template in Amazon Athena Federated Query prior to v2026.17.1, there is incorrect privilege assignment. An authenticated remote user can read arbitrary AWS Secrets Manager secrets in the deploying account by pointing the connector's connection string at an unrelated secret and at a database endpoint under the user's control, causing the connector to transmit the secret to that endpoint.
Risk Assessment
The vulnerability can lead to leakage of sensitive data, such as AWS secrets, which could compromise the security of the entire account.
Recommendation
It is recommended to upgrade aws-athena-query-federation connectors to version v2026.17.1 or later and ensure any forked or derivative code is patched. Alternatively, redeploy the connector with the current template and supply a non-empty SecretNamePrefix value.

- CVE-2026-124494Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability because the html.clean() sanitizer's _normalizeURL() function decodes named entities like : to an empty string. Attackers can inject href values such as javascript: that pass the _isSafeURL() check but are decoded by browsers, executing JavaScript when victims click stored links.
- CVE-2026-124493Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability in the DocumentType constructor that injects header textContent into innerHTML without HTML escaping. Attackers can store entity-encoded HTML in h1-h6 headers that executes JavaScript when editors using document:header mode initialize, enabling session cookie theft.
Original NVD description (English source)
Incorrect privilege assignment in the ClickHouse connector deployment template in Amazon Athena Federated Query prior to v2026.17.1 could allow an authenticated remote user to read arbitrary AWS Secrets Manager secrets in the deploying account by pointing the connector's connection string at an unrelated secret and at a database endpoint under the user's control, causing the connector to transmit the secret to that endpoint. To remediate this issue, users should upgrade to aws-athena-query-federation connectors version v2026.17.1 or later and ensure that any forked or derivative code is patched to incorporate the new fixes. Alternatively, to remediate this issue, users should redeploy the connector with the current template and supply a non-empty SecretNamePrefix value.
