In affected versions OpenPGP Cleartext Signed Messages are cryptographically signed messages where the signed text is readable without special tools. These messages typically contain a \"Hash: ...\" header declaring the hash algorithm used to compute the signature digest. OpenPGP.js up to v5.9.0 ignored any data preceding the \"Hash: ...\" texts when verifying the signature. As a result, malicious parties could add arbitrary text to a third-party Cleartext Signed Message, to lead the victim to believe that the arbitrary text was signed. A user or application is vulnerable to said attack vector if it verifies the CleartextMessage by only checking the returned `verified` property, discarding the associated `data` information, and instead _visually trusting_ the contents of the original message. Since `verificationResult.data` would always contain the actual signed data, users and apps that check this information are not vulnerable. Similarly, given a CleartextMessage object, retrieving the data using `getText()` or the `text` field returns only the contents that are considered when verifying the signature. Finally, re-armoring a CleartextMessage object (using `armor()` will also result in a \"sanitised\" version, with the extraneous text being removed. This issue has been addressed in version 5.10.1 (current stable version) which will reject messages when calling `openpgp.readCleartextMessage()` and in version 4.10.11 (legacy version) which will will reject messages when calling `openpgp.cleartext.readArmored()`. Users are advised to upgrade. Users unable to upgrade should check the contents of `verificationResult.data` to see what data was actually signed, rather than visually trusting the contents of the armored message."}],"source":{"advisory":"GHSA-ch3c-v47x-4pgp","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T18:46:11.562Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/openpgpjs/openpgpjs/security/advisories/GHSA-ch3c-v47x-4pgp","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/openpgpjs/openpgpjs/security/advisories/GHSA-ch3c-v47x-4pgp"},{"name":"https://github.com/openpgpjs/openpgpjs/commit/6b43e02a254853f5ff508ebd1b07541f78b7c566","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/openpgpjs/openpgpjs/commit/6b43e02a254853f5ff508ebd1b07541f78b7c566"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-09-30T17:34:19.116832Z","id":"CVE-2023-41037","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-09-30T17:43:47.802Z"}}]}}
