Escargot · Vulnerability

CVSS 3.1 5.7 MEDIUMCheck source for fixed versionsKEV status unknown

cve-program · CVE-2026-124684

Published

A use-after-free vulnerability exists in Samsung Escargot 5.0.2 in the buffer-access paths for ReloadableString and CompressibleString. Internal raw character accessors and the public StringRef::stringBufferAccessData() API did not preserve the lifetime of the underlying buffer while it remained in use. As a result, idle unloading or garbage-collection compression could release the buffer and leave a stale pointer. Subsequent access may cause the process to crash or, under allocation-dependent conditions, expose limited contents of another heap allocation. The issue was addressed by adding buffer-lifetime reference tracking and removing unsafe raw character accessors.

Affected versions, risk and source history

Exploitation and risk

Source status

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

Risk history

Compare earlier KEV listings and daily EPSS scores. Advisory wording and affected versions have a separate history.

When does an EPSS score appear as a change?

A prediction change is reported when EPSS rises from below 10% to 10% or higher. Other daily score changes remain in this history.

Advisory history

4 saved versions

See how the publisher's advisory changed over time. Each link opens the version saved at that time. The publisher's update date can differ from the date shown here.

How advisory history works

Each link identifies one complete publisher record. History can include advisories that previously shared an identifier; an identifier removed by a publisher no longer establishes a current relationship. A historical link shows only that record and earlier saved versions. Failed checks and unchanged reads do not create new versions.
