lightning-types: replace Zl/Zp separators in `PrintableString`

This commit fixes a log-forgery risk in a Rust Lightning library helper called PrintableString. That helper is meant to make untrusted text safe to print by replacing dangerous characters with a placeholder. It already caught most control …

blinded_path: only compact introduction nodes via channels enabled both ways

This change fixes a bug in how Lightning blinded paths choose a compact reference to the introduction node. Previously, the code could pick an old channel that was disabled or effectively closed, making the resulting BOLT 12 offer or blind…

fuzz: add a payer proof deserialization target

This commit only adds a new fuzz test target. Fuzz tests are automated tools that throw random or crafted input at a piece of code to look for crashes or bugs. The commit does not change any production code, protocol behavior, or user-faci…

offers: add BOLT 12 payer proof primitives

This commit adds a new feature to rust-lightning called BOLT 12 payer proofs. It lets someone who paid a BOLT 12 invoice cryptographically prove they paid it, while optionally hiding some invoice details. The change is a large new module p…

refactor(offers): extract payer key derivation helpers

This commit is a code cleanup (refactor) in the Lightning Dev Kit library. It moves existing payer key-derivation logic into shared helper functions so that future 'payer proof' features can reuse the same code. The change does not appear …

ln: persist the paid BOLT 12 invoice and build payer proofs

This commit is a feature addition, not a vulnerability fix. It extends rust-lightning's BOLT 12 payment support so that when a wallet pays a BOLT 12 invoice, the paid invoice is saved through retries and restarts and is later exposed in th…

fix: release txprepare reservations on send failure

This commit fixes a bug in Core Lightning's wallet code where, if a prepared Bitcoin transaction failed during signing or broadcast, the coins that had been set aside ('reserved') for that transaction were not released back to the wallet. …

Denial-of-service/availability impact: failed transactions could leave wallet UTXOs permanently reserved, preventing their reuse until manual interventionResource exhaustion pattern: reserved inputs are not spendable, so repeated failed sends could reduce usable wallet balanceError-path resource cleanup (CWE-772, CWE-404): missing release of reserved inputs on failure
