CVE-2026-74785
MediumCVSS 6.5Exploitation Probability (EPSS)
Low risk20th percentile - higher than 20% of all known CVEs
Summary
Scriban before 7.0.0 contains three distinct denial-of-service vulnerabilities in expression evaluation that bypass existing safety controls through unbounded string multiplication, uncontrolled BigInteger shift operations, and LoopLimit bypass via range enumeration in builtin functions. Attackers who can supply templates can cause out-of-memory exceptions or CPU exhaustion, typically terminating the entire host process.
Risk Assessment
An attacker can cause application crash or resource exhaustion, leading to service disruption and potential availability loss.
Recommendation
Upgrade Scriban to version 7.0.0 or later, which includes fixes for all three vulnerabilities.
