Trivy's own label is CRITICAL. Rated critical by GHSA.

Description

The PDO adapters of Zend Framework 1 do not filter null bytes values in SQL statements. A PDO adapter can treat null bytes in a query as a string terminator, allowing an attacker to add arbitrary SQL following a null byte, and thus create a SQL injection. We tested and verified the null byte injection using pdo_dblib (FreeTDS) on a Linux environment to access a remote Microsoft SQL Server, and also tested against and noted the vector against pdo_sqlite.

Inside your cluster, without you opening a spreadsheet.

KnowsThe scanner refreshes its vulnerability database every six hours.
FindsEvery admitted image is rescanned every 24 hours by default (scan.rescanInterval). When Trivy rates this vulnerability critical for the image's package source, it appears in the image's findings by name. Findings without a fix are left out unless includeUnfixed is on.
Tells youA critical_finding event goes to the channels subscribed to it: e-mail, Slack, Teams, a webhook, Jira, GitLab or GitHub.
RefusesWith a policy that blocks critical findings, a pod with this image is refused at admission, a rollback to it included. Pods already running are not evicted.
RecordsEach decision is recorded with the policy that ran and its hash, then sealed under a signed checkpoint.
