Descripción técnica

In Eclipse Vert.x versions [4.0.0, 4.5.34] or [5.0.0,5.0.12] or [5.1.0,5.1.9] or [5.2.0, 5.2.0], a gRPC endpoint does have a configurable per message maximum size in bytes, however the maximum size applies to the received bytes. When applied to a compressed message, this only applies to the compressed size and not the actual size of the uncompressed content. This can be used to force a gRPC endpoint to allocate more bytes than the value defined by the configuration, making the endpoint vulnerable to compression bomb attacks. The impacted component is io.vertx:vertx-gprc-server.

——0Pillow is a Python imaging library. From 4.1.0 until 13.0.0, Pillow's MSP RLE decoder can expand a small file into an unbounded in-memory buffer. The decoder writes run-length output to BytesIO without limiting expansion to the declared image size. An attacker can supply a crafted MSP image to an application that loads its pixels. This can exhaust memory and deny service even when the declared pixel count passes the decompression-bomb check. This issue is fixed in version 13.0.0.14h CVE-2026-1119247.5 ALT

——8Fleet before 4.83.0 contains a denial of service vulnerability that allows unauthenticated attackers to exhaust server memory by sending gzip-compressed request bodies. Attackers can send small, highly compressed requests with Content-Encoding: gzip to unauthenticated endpoints that expand during decoding, crashing the entire Fleet instance.14h CVE-2026-1020726.5 MED

——10An Improper Handling of Highly Compressed Data vulnerability in the gRPC library used by na-grpcd of Juniper Networks Junos OS allows an authenticated network-based attacker to cause a denial of service via a compressed gRPC request.5d CVE-2026-1026958.2 ALT

——7OmniFaces is a utility library for Faces. In OmniFaces versions before 1.14.3, 2.7.33, 3.14.23, 4.7.12, and 5.4.2, CombinedResourceHandler accepts a structurally valid deflated and base64 encoded combined resource ID without verifying that the server issued it. A forged ID can cause unbounded decoded output, add unique reconstructed IDs to a process-lifetime cache, or combine resources other than stylesheets and scripts. Because jakarta.faces.RESOURCE_EXCLUDES is not applied by this custom resolution path, a forged ID can disclose Facelets source from the webapp resource tree or META-INF/resources. In a deployment configured with the wildcard CDN mapping, a forged ID that selects omnifaces.graphic can also cause a blind, deployment-dependent server-side fetch whose destination derives partly from the request Host header. The flaw does not provide arbitrary file read or establish arbitrary-scheme or arbitrary-destination SSRF. The shared authenticity failure permits memory exhaustion and limited resource disclosure. This issue is fixed in versions 1.14.3, 2.7.33, 3.14.23, 4.7.12, and 5.4.2.10h CVE-2026-955025.3 MED
