CVE-2026-91097 is one of multiple externally reported vulnerabilities remediated in HP Linux Imaging and Printing (HPLIP) software components. The specific vulnerable component, flaw class, and exploitation conditions for this individual CVE are not available. Affected package sets reported by detection content include hplip, hplip-common, hplip-gui, hplip-libs, hpijs, and libsane-hpaio on CentOS 7 and 8 and Red Hat Enterprise Linux 7, 8, 9, and 10.

2 valid exploits after Mallory filtered fakes, detection scripts, and README-only repos.
The repository contains one executable Python mass-exploitation tool, HPLIP.py, plus a restrictive license and a detailed README. HPLIP.py uses requests with TLS verification disabled, normalizes a supplied target list, tries HTTP/HTTPS targets (defaulting to port 8000), fingerprints HPLIP/PAPPL version information, and processes targets concurrently. For detected HPLIP Printer Application instances earlier than 3.26.6 with no configured administrator password, it performs a chained unauthenticated administrative workflow against /config, /network, /tls-install-crt, /plugin, /logfile.txt, and /security. It records successes in five local text files. The documented plugin sequence invokes installation and license acceptance for an HP plugin; it is described as causing execution of the downloaded .run installer on the target, but the repository does not include an attacker-controlled arbitrary-command or shell payload. README usage refers to T.py, while the actual entry-point filename in the repository is HPLIP.py.
This 11-file Python repository is a mass HPLIP surface scanner and research exploit driver for CVE-2026-91097 through CVE-2026-91106. `poc.py` is the primary CLI entry point: it accepts an individual target or target list, concurrently scans selected ports, writes JSONL results, and optionally runs CVE-class-specific exploit attempts. `cve_catalog.py` defines the affected-version threshold (3.26.6), CVE metadata, and filtering logic. `hplip_probes.py` implements TCP reachability checks plus hpssd, IPP/CUPS HTTP, and JetDirect/PJL fingerprints. `fofa_to_list.py` converts FOFA exports into normalized host:port input lists. Exploit logic is in `hplip_exploit.py`. For the claimed hpssd command-injection class, it sends a SOAP/XML EmailEvent whose email field injects an operator-provided command and a marker, then checks returned text for the marker or `uid=`/`gid=` output. For heap-related classes on raw TCP services, it sends an oversized XML field and only treats reset/error behavior as a weak crash indication. For PAPPL/HPLIP Printer Application services, it discovers an IPP printer URI and submits an IPP Print-Job with the crafted PWG raster built by `pappl_raster.py`; `pappl_ipp.py` provides the minimal binary IPP encoder. The code itself acknowledges that the PAPPL raster path is research-only, does not yield HTTP shell output, and cannot confirm RCE. The project is not part of Metasploit, Nuclei, or another recognized exploit framework. Its active network payloads make it more than a detection script, but its exploitation is basic and mostly unverified: command execution relies on a legacy service behavior, while the heap/PAPPL paths are crash or acceptance probes without a reliable control-flow/RCE chain.
