D9l18a Firmware
Monthly
HP OfficeJet Pro printers (D9l18a, D9l20a, D9l21a, D9l63a firmware) are vulnerable to information disclosure through CORS misconfiguration when administrators enable the feature on the Embedded Web Server. An unauthenticated remote attacker can exploit this to access sensitive device resources from untrusted web origins. CORS remains disabled by default as a mitigation, but organizations that have explicitly enabled it should apply patches when available.
HP OfficeJet Pro printers running affected firmware versions are susceptible to denial of service attacks through malformed Internet Printing Protocol (IPP) requests that prevent proper TCP connection establishment. An unauthenticated remote attacker can trigger this condition to disrupt printer availability, though no patch is currently available to mitigate the vulnerability.
