Datadog dd-trace-py: IAST instrumentation can lead to application DOS
GitHub lists this reviewed advisory for ddtrace. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

### Summary A flaw in dd-trace-py’s IAST instrumentation can cause the Python application process to terminate unexpectedly when processing certain attacker-controlled input. Only applications with IAST enabled are affected. IAST is disabled by default. ### Details The affected IAST string-processing instrumentation does not properly handle certain internal errors, allowing an error to terminate the application process. Exploitation requires IAST to be enabled and application code to perform an affected string-processing operation on attacker-controlled input. If you are unable to upgrade to a patched version of dd-trace-py, you can mitigate this issue by either disabling IAST (setting DD_IAST_ENABLED=false) or by replacing replace % string interpolations with str.format or f-strings for user inputs in your monitored application. ### Proof of concept Detailed triggering inputs and reproduction steps are omitted from this advisory. The linked fix (#20786) includes regression coverage for the affected behavior. ### Impact Denial of service affecting applications that use a vulnerable version of dd-trace-py with IAST enabled and expose the affected operation to attacker-contro
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
