fflate through 0.8.2 is vulnerable to denial of service via an infinite loop in unzipSync(). A crafted ZIP archive with a central directory entry declaring compressed_size=0xFFFFFFFF (ZIP64 sentinel) but missing the required ZIP64 extra field tag 0x0001 causes z64e() to loop indefinitely due to out-of-bounds reads returning undefined, which coerces to 0, keeping the loop condition permanently true.

CVE-2026-65545.5 MED—
———libpcap BPF interpreter treats the offset in the 'ja L' BPF instruction as a signed integer to implement looping via backward jumps, but it does not limit the number of loop iterations. In particular uncommon use cases a crafted filter program can cause the interpreter to loop infinitely.7hCVE-2026-857036.5 MED—
——0A flaw has been found in ramon-victor freegpt-webui up to 098db3dfeb41555c2ca9269df0f13e10ec1c35dc. Affected by this issue is the function getJailbreak of the file server/backend.py of the component Jailbreak Mode. Executing a manipulation can lead to allocation of resources. The attack can be executed remotely. The exploit has been published and may be used. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable. This vulnerability only affects products that are no longer supported by the maintainer.1dCVE-2026-555125.3 MED—
——0nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN. From version 0.2.0 to before version 0.5.0, when OIDC is enabled, GET /ui/oidc/login is reachable without authentication and is registered outside the Web UI rate-limited auth routes. Every request creates a fresh random OIDC state value and stores it in an in-memory map for 10m. Expired states are swept lazily, but there is no rate limit or maximum live-state cap on the allocation path. An unauthenticated remote client can therefore grow OIDC.states for the full state TTL, bounded by request throughput rather than by configured auth rate limits. This issue has been patched in version 0.5.0.1dCVE-2021-443207.5 HIG—
——0Parrot AR.Drone version 1 and 2 does not employ a suitable mechanism to prevent denial-of-service (DoS) attacks. An attacker can harm the device availability (i.e., video streaming and control) by using tool to perform an IPv4 flood attack. Verified attacks includes SYN flooding and UDP flooding.1dCVE-2026-85730——
——0smol-toml is a small, fast, and correct TOML parser and serializer. Prior to 1.7.1, parse() can enter an infinite loop when a value inside an array or inline table is followed by a comment with no trailing newline. In src/util.ts, skipUntil() calls indexOfNewline(), receives -1 at the end of input, and resets the cursor to the beginning of the string instead of leaving the structure scan. The parser then hangs indefinitely and can consume a service's processing capacity when an application parses attacker-controlled TOML. This issue is fixed in version 1.7.1.1dCVE-2026-785435.3 MED—
——0IBM App Connect Enterprise 13.0.1.0 through 13.0.8.1, and 12.0.1.0 through 12.0.12.28 and IBM Integration Bus for z/OS 10.1.0.0 through 10.1.0.7 could allow a remote attacker to cause a denial of service due to an infinite loop.1d
