Summary

CVE-2026-1330 is a high-severity Absolute Path Traversal (CWE-36) vulnerability in Hamastar Meetinghub Paperless Meetings. Its CVSS base score is 8.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 44.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SC-14 (Public Access Protections) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2026-1330 is an Arbitrary File Read vulnerability affecting MeetingHub, a product developed by HAMASTAR Technology. The flaw enables Absolute Path Traversal, allowing attackers to download arbitrary system files. Published on 2026-01-22, it is rated with a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) and maps to CWE-36.

Unauthenticated remote attackers can exploit this vulnerability over the network with low attack complexity, requiring no privileges, user interaction, or scope changes. Successful exploitation grants high-impact confidentiality violations by enabling the retrieval of sensitive system files.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
attack.mitre.org →
T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.
attack.mitre.org →
Why these techniques?

Arbitrary file read via path traversal on a network-accessible application directly enables remote exploitation of a public-facing service (T1190) and retrieval of sensitive local system files (T1005).

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Implements input validation mechanisms at file access points to block absolute path traversal attempts and prevent arbitrary file reads.

SC-14 Public Access Protections good match
prevent

Enforces security safeguards on public interfaces to prevent unauthenticated access to non-public system files via path traversal.

AC-3 Access Enforcement partial match
prevent

Mandates enforcement of access control policies to restrict logical access to system files, mitigating unauthorized reads exploited through the vulnerability.
