Security Vulnerabilities
Apache Airflow's `/assets/events` API returned asset events for every Dag in the deployment, with no filter restricting them to the Dags the caller is authorized to read. Any authenticated user holding asset-read access could therefore enumerate asset events — including the source Dag ID, task ID, run ID and event timestamps — for Dags they have no permission to see. Because the filter was also absent from the count query, `total_entries` and pagination disclosed the existence of hidden Dags even without inspecting individual rows. Deployments are affected whenever per-Dag access control is used to separate teams or tenants; no special configuration is required. Upgrade to apache-airflow 3.3.2 or later.

A specially crafted pair of WS-Policy documents can force Neethi's policy-intersection to do exponential amounts of work, pinning the CPU for a long time (denial of service).
Users are recommended to upgrade to version 3.2.4, which fixes this issue.

When Neethi fetches a remote policy reference, it only limits the time per read, not the whole transfer, so a server that trickles bytes slowly can keep the fetch alive indefinitely and tie up the calling thread (denial of service).
Users are recommended to upgrade to version 3.2.4, which fixes this issue.

A specially crafted WS-Policy document with deeply nested policy elements can bypass Neethi's nesting-depth limit and exhaust the thread stack, crashing the parser (denial of service).

A specially crafted WS-Policy document can pack unlimited content inside a policy assertion, which Neethi copies into memory without counting it against its size limits, exhausting the heap (denial of service).

A small WS-Policy document using repeated policy references can force Neethi to re-expand the same references exponentially during normalization, consuming huge amounts of CPU and memory (denial of service).
Users are recommended to upgrade to version 3.2.4, which fixes this issue.

Suricata before 8.0.7 has a DoH2 type confusion that can cause an invalid free, because cleanup code for the HTTP2 state is executed even though the actual state is HTTP1 (when there is a DoH2 request with an HTTP1 to HTTP2 upgrade). This requires app-layer.protocols.doh2 to be enabled, which is the default in 8.x versions.

Suricata before 8.0.7 has an Http2ThreadMultiBuf use-after-free when a transaction is inspected by rules that use http.response_header with and without a transform.

Exim before 4.100.1 allows SMTP smuggling in which the received message does not match any sent message, and instead depends on crafted data sent after a rejection during DATA processing.
