CVE-2026-75505: EspoCRM: Access control bypass in Mass Update letting regular user with Mass Update permission read any attachment

MediumCVSS 6.0 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 24/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.29% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: espocrm espocrm 10.0.2.

Low priority for now. Upgrade to espocrm espocrm 10.0.2 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

EspoCRM is an open source customer relationship management application. Prior to 10.0.2, an authenticated user with mass-update permission can supply a known attachment identifier to the mass-update functionality. The mass-update processor duplicates the attachment without checking whether the caller can read it, bypassing record-level and field-level restrictions and exposing the file contents through the copied attachment. Obtaining a valid attachment identifier may be difficult. This issue is fixed in version 10.0.2.
