A fix is available — apply it.

Integer overflow in util.c in mod_dav_svn in Apache Subversion 1.7.x, 1.8.x before 1.8.15, and 1.9.x before 1.9.3 allows remote authenticated users to cause a denial of service (subversion server crash or memory consumption) and possibly execute arbitrary code via a skel-encoded request body, which triggers an out-of-bounds read and heap-based buffer overflow.

Exploitation public PoC (EG-KEV: elevated) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
