Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

NewCVE-2026-24889 (opens in a new tab)How to fix?
Upgrade soroban-sdk to version 22.0.9, 23.5.1, 25.0.2 or higher.
Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the Bytes::slice, Vec::slice, or Prng::gen_range functions. An attacker can corrupt contract state or cause unintended behavior by supplying user-controlled or computed range bounds that trigger arithmetic overflow.
Note:
This is only exploitable if overflow-checks = false is set either explicitly or implicitly in the contract configuration.
Workaround
This vulnerability can be mitigated by enabling overflow checks in the contract workspace profile or by validating range bounds before passing them to slice or gen_range.
