Vulnerability from github – Published: 2025-03-14 17:31 – Updated: 2025-03-15 20:47

Summary

In Azle, calling `setTimer` causes infinite loop of timers

Details

Impact

Calling setTimer in Azle versions 0.27.0, 0.28.0, and 0.29.0 causes an immediate infinite loop of timers to be executed on the canister, each timer attempting to clean up the global state of the previous timer.

The infinite loop will occur with any valid invocation of setTimer.

Patches

The problem has been fixed as of Azle version 0.30.0.

Workarounds

If a canister is caught in this infinite loop after calling setTimer, the canister can be upgraded and the timers will all be cleared, thus ending the loop.

Severity

8.7 (High)

Title

Azle calling `setTimer` causes infinite loop of timers

Summary

Azle is a WebAssembly runtime for TypeScript and JavaScript on ICP. Calling `setTimer` in Azle versions `0.27.0`, `0.28.0`, and `0.29.0` causes an immediate infinite loop of timers to be executed on the canister, each timer attempting to clean up the global state of the previous timer. The infinite loop will occur with any valid invocation of `setTimer`. The problem has been fixed as of Azle version `0.30.0`. As a workaround, if a canister is caught in this infinite loop after calling `setTimer`, the canister can be upgraded and the timers will all be cleared, thus ending the loop.
