CVE-2026-72678

Elasticsearch does not validate a size value taken from a user-supplied input before that value is used to reserve memory for an internal data structure. An authenticated user holding only read privileges can submit a single small crafted request to a product API endpoint that causes the node to...

CVE-2026-72687 Memory Allocation with Excessive Size Value in Elasticsearch Leading to Denial of Service

A flaw in Elasticsearch allows a low-privileged authenticated user to submit a single small request containing a forged opaque identifier. Elasticsearch decodes and deserializes the identifier before confirming that it was legitimately issued by the cluster, and a size value carried inside the...

CVE-2026-72684

This CVE affects Elasticsearch where an authenticated user with read privileges can trigger memory allocation by sending a crafted small search input, leading to an out-of-memory fatal condition and node denial of service. Affected versions: 8.0.0–8.19.19 and 9.0.0–9.4.4. Mitigation: upgrade to v...

CVE-2026-72684 Allocation of Resources Without Limits or Throttling in Elasticsearch Leading to Denial of Service

A flaw in Elasticsearch allows an authenticated user holding only read privileges to submit a small search request containing a crafted user-supplied input. Processing that input causes a specific internal component to allocate memory without any upper bound, and the allocation occurs outside the...

CVE-2026-14677 PostgreSQL 32-bit pltcl and plperl undersize allocations, via integer wraparound

Integer wraparound in PostgreSQL 32-bit builds of pltcl and plperl allows an object creator to cause the server to undersize an allocation and write out-of-bounds via crafted function bodies. This may execute arbitrary code as the operating system user running the database. CVE-2026-6473 had fixe...
