Remote authenticated users can crash applications built on Amazon aws-sdk-cpp versions before 1.11.862 by supplying crafted Base64-encoded input that triggers an out-of-bounds read in the SDK's Base64 decoder. Exploitation is constrained to authenticated users, requires high attack complexity, and is platform-specific - not all deployments are vulnerable. The CVSS 4.0 vector (VA:H, VC:N, VI:N) confirms impact is limited to availability (denial of service); no public exploit code exists and the vulnerability is not listed in the CISA KEV catalog at time of analysis.
Out-of-bounds write in the Base64 decoder of Amazon's aws-sdk-cpp (all versions before 1.11.862) exposes applications to heap memory corruption or crash when processing attacker-supplied Base64-encoded content. Remote authenticated attackers can trigger the defect by submitting crafted input to any application built on this SDK that routes user-controlled data through the affected decoder path. No public exploit code has been identified at time of analysis, and the vulnerability has not been added to the CISA KEV catalog, though the CWE-787 heap write class carries inherent tail risk beyond the denial-of-service primary impact.
