Core Lightning v26.06.9: urgent loss-of-funds security update

Core Lightning says v26.06.9 fixes a newly reported vulnerability that can lead to loss of funds. The release also contains security fixes in channel reestablishment, splicing, HTLC shutdown handling, onion and on-chain handling, gossip range queries, runes, configuration, and several remote-crash and hardening fixes.

Affected: Every Core Lightning node running v26.06.8 or earlier is affected, according to the vendor. Technical tests for the security fixes are temporarily withheld to slow exploit development while operators upgrade.

Action: Upgrade to Core Lightning v26.06.9 immediately. Download the release from https://github.com/ElementsProject/lightning/releases/tag/v26.06.9, verify the appropriate signed SHA256 manifest and checksums for your architecture, install it, restart lightningd, and confirm the running version.

Liquid Network: ~4,000 BTC withdrawn in critical peg incident

Liquid confirms that purported white-hat actors withdrew roughly 4,000 BTC (about $320 million) from its federation wallet through the SideSwap PAK. Liquid says the PAK and other federation keys were not compromised. The actors have not yet returned the funds. Independent public analysis points to a newly introduced range-proof cache-key flaw, but Liquid has not yet published its root-cause report.

Affected: The L-BTC peg and Liquid federation reserves are affected. Bridge nodes are disabled, the sidechain is paused, and exchanges have suspended L-BTC deposits and withdrawals. Liquid says other issued assets, including USDT, DePix, and RWAs, are unaffected; Bitcoin's base layer is not affected.

Action: Do not initiate Liquid peg-ins, peg-outs, swaps, or L-BTC exchange deposits or withdrawals while the network is paused. Follow official Liquid and Blockstream updates, and treat L-BTC peg exposure as impaired until reserves are restored and a verified fix and incident report are published.

BTCPay Server: actively exploited LND credential theft

BTCPay confirms that an unauthenticated remote attacker could obtain LND .macaroon credentials, take control of affected LND nodes, and move funds. The vendor reports confirmed exploitation and stolen funds.

Affected: BTCPay Server versions before 2.4.2, including 2.4.2 release candidates, when used with LND. BTCPay says other Lightning implementations are not exposed to this specific credential risk.

Action: Update to BTCPay Server 2.4.2 and LND 0.21.1 immediately, review node activity, and rotate credentials. If you cannot update now, take the affected server offline.

refactor(core): merge passphrase__access_hidden_wallet into passphrase__access_wallet

This commit is a simple user-interface cleanup. It removes one duplicate translation label ('Access hidden wallet') and makes the device use a single, consistent label ('Access wallet') when asking the user to confirm opening a passphrase-…

contrib: add jaonoctus's signing key

This commit simply adds a new person's PGP public-key fingerprint to the list of trusted release signers in two documentation files. It does not change any code, fix any bug, or alter any security behavior of the software itself.

Why commit watching?

Security should leave a paper trail.

A quiet fix may be responsible caution—or it may leave users unaware that their assets were ever at risk. CommitWatch preserves the evidence, adds context, and tracks whether vendors disclose, acknowledge, and learn.
