OpenPGP.js teegis on tuvastatud haavatavus (CVE-2025-47934), mis v\u00f5imaldab r\u00fcnnakuj\u00f5ul saata muudetud s\u00f5num, mida saadetakse saajale kinnitatud t\u00f5endina (openpgp.verify ja openpgp.decrypt funktsioonid tagastavad eduka digitaalse allkirja kontrollimise, kuigi sisu on asendatud ja erineb andmetest, mille jaoks allkiri loodi). Haavatavus on k\u00f5rvaldatud OpenPGP.js versioonides 5.11.3 ja 6.1.1. Probleem esineb ainult OpenPGP.js 5.x ja 6.x harudes ning ei m\u00f5juta OpenPGP.js 4.x versiooni. <\/p>\n

OpenPGP.js teek pakub iseseisvat rakendust OpenPGP protokollile JavaScriptis, v\u00f5imaldades brauseris \u0161ifreerimise toimingute tegemist ja digitaalsete allkirjadega t\u00f6\u00f6tamist avatud v\u00f5tmete alusel. Projekti arendavad Proton Maili arendajad ja seda kasutatakse mitte ainult s\u00f5numite t\u00e4ieliku \u0161ifreerimise korraldamisel Proton Mailis, vaid ka sellistes projektides nagu FlowCrypt, Mymail-Crypt, UDC, Encrypt.to, PGP Anywhere ja Passbolt. <\/p>\n

Haavatavus m\u00f5jutab elektroonilise allkirja verifikatsiooni menetlusi (openpgp.verify) ning allkirjastatud ja \u0161ifreeritud s\u00f5numeid (openpgp.decrypt). R\u00fcndaja v\u00f5ib kasutada olemasolevaid allkirjastatud s\u00f5numeid uute s\u00f5numite loomiseks, mille de\u0161ifreerimisel r\u00fcnnet m\u00f5jutavas OpenPGP.js versioonis saadakse asendatud sisu, mis erineb algsest allkirjastatud s\u00f5numist. Haavatavus ei m\u00f5juta allkirju, mis levitatakse eraldi tekstist (probleem avaldub ainult allkirja edastamisel koos tekstiga \u00fche andmepakina). <\/p>\n

Asenduss\u00f5numi loomiseks piisab r\u00fcndajast, kellel on juurdep\u00e4\u00e4s \u00fchele allkirjastatud v\u00f5i eraldiseisvale allkirjale, samuti teadlikkus sellest, mis andmed on selles s\u00f5numis allkirjastatud. R\u00fcndaja saab s\u00f5numit muuta nii, et muudetud versiooni allkiri loetakse endiselt kehtivaks. Samuti on v\u00f5imalik muuta allkirjastatud ja \u0161ifreeritud s\u00f5numeid, mille de\u0161ifreerimisel tagastatakse r\u00fcndaja lisatud andmed.
