Librsvg: use-after-free when xml includes have duplicated entities
Collected exploitation and prediction evidence
Risk source coverageCISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.
No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.
cve-program · CVE-2026-96889
PublishedA flaw was found in librsvg. When processing an SVG document containing nested XML inclusions (Xincludes) with duplicate entity declarations, a use-after-free error can occur. This vulnerability arises because the library incorrectly frees an XML entity that is still in use by the parser. An attacker could potentially exploit this to cause a denial of service or execute arbitrary code.

PublishedLibrsvg uses libxml2, a C library, to parse XML. When librsvg parses an SVG document which has a nested Xinclude, an XML entity declaration with a duplicate name as an existing one can cause a use-after-free error. While libxml2 is expanding an internal entity, a recursive XInclude can parse another document that declares an entity with the same name. Both parses use the same `XmlState` entity map on the librsvg side. `entity_insert()` replaces the first entry, whose `Drop` implementation calls `xmlFreeNode()`. The outer `xmlCtxtParseEntity()` then keeps using the freed 144-byte `xmlEntity`. The included parse should not free an entity that the outer parser is still using. The fix is in commit 8a1b0cd319e9af2d1e9cf878081dd77f227a0504, where librsvg will no longer free xmlEntity pointers that libxml2 is still using.
