ETK-2026-311Zero's internal tracking ID, independent of the CVE number.
waiting for further signalsZero needs more public information before it can validate it.description
Affected npm devalue versions can turn a small value into a very large serialized string when data processed with parse is later passed to uneval. An attacker able to influence data in that processing flow may cause excessive serialized output and associated resource use.
mitigation
Upgrade npm devalue to version 5.9.3 or later. Until upgrading, avoid passing untrusted or attacker-influenced parsed data to uneval.
fixed in 5.9.3
outcome
No artifact: an exploit or check was attempted but could not be produced at this moment.
