CVE-2026-85786 Incomplete fix for CVE-2026-75936 memory-amplification denial of service in Amazon ion-java

Improper handling of highly compressed data in Amazon ion-java before 1.12.1 might allow remote attackers to cause a denial of service via a crafted compressed Ion document that expands to an arbitrarily large size upon decompression due to insufficient coverage of the GZIP auto-decompression...

CVE-2026-85786

Amazon ion-java before 1.12.1 contains an incomplete fix for CVE-2026-75936, a memory-amplification denial-of-service vulnerability. The root cause is insufficient coverage of the GZIP auto-decompression opt-out that was introduced to address CVE-2026-75936, allowing a remote attacker to supply a...

GHSA-WGWX-479J-23VQ SiYuan: Missing authorization on refreshBacklink allows anonymous readers to trigger persistent server-side writes and unauthenticated resource amplification (publish mode)

CVE: This vulnerability corresponds to CVE-2026-72812. Summary The /api/ref/refreshBacklink endpoint is gated by CheckAuth only. Unlike its mutating siblings, it carries no CheckAdminRole, no CheckReadonly, and no inline reader-role guard so it falls through all three authorization mechanisms the...
