CVE-2026-29795 describes a vulnerability in the stellar-xdr library (versions prior to 25.0.1) where the StringM::from_str function fails to validate input string length against its declared maximum. This allows the creation of oversized StringM objects, violating length invariants and potentially leading to unexpected behavior in downstream serialization or validation processes. Rated as Medium severity (CVSS 4.0), it has a local attack vector with low complexity and a low impact on integrity. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
