CVE-2026-1997 — Certain HP OfficeJet Pro Printers - Information Disclosure

Certain HP OfficeJet Pro printers may expose information if Cross‑Origin Resource Sharing (CORS) is misconfigured, potentially allowing unauthorized web origins to access device resource. CORS is disabled by default on Pro‑class devices and can only be enabled by an administrator through the Embedded Web Server (EWS). Keeping CORS disabled unless explicitly required helps ensure that only trusted solutions can interact with the device.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.2% (30-day exploitation probability)+2
Technical severity (medium)+3
Automatable exploitation (SSVC)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Hp D9l18a Firmware, Hp D9l20a Firmware, Hp D9l21a Firmware…).
The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Search available logs for exploit probes, errors and authentication anomalies.

What should defenders know first?

CVE-2026-1997 is "Certain HP OfficeJet Pro Printers - Information Disclosure", rated Medium. It affects D9l18a Firmware (Hp); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 5.3 describes technical severity. EPSS 0.22% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
