Core Lightning, the Blockstream ElementsProject Lightning implementation, shipped version 26.06.7 on August 28 as an emergency security release after confirming multiple vulnerabilities from AI-generated reports over roughly the past three weeks, including a concentrated stretch of findings that began around mid-August. Full vulnerability details and source code remain under a 14-day embargo so node operators can upgrade before potential exploits become public, with the window expected to close in mid-September. Operators are told to download and verify signed platform tarballs for amd64 and arm64 builds using checksums and GPG signatures, unpack them over the existing installation, and restart lightningd; the update needs no manual database migration because required steps run automatically at startup. Developers explicitly warned against waiting for Docker images that were unavailable at launch, while operators who cannot upgrade immediately should use the --offline flag to keep chain monitoring without network-facing exposure. The release follows 26.06.6 from July 22 and is branded "Quantum-Resistant Lightning Channel VII." Versions 26.04 and earlier are no longer supported, no formal CVEs had been published by late August, version 26.09 remains scheduled for September, and no confirmed fund losses or active exploitation have been reported under the binaries-first disclosure approach.
