Ordinary READ permission means PR:L not PR:H; supplying another record's id is trivial (AC:L); confined to app data (S:U); read-only PII disclosure so C:H, I:N, A:N.

DescriptionCVE.org

CordysCRM is an open source AI-powered customer relationship management system that supports private deployment. Prior to 1.7.4, GET /pool/lead/get/{id} in PoolClueController.get and GET /pool/account/get/{id} in PoolCustomerController.get use bare pool-read permission checks without the CsPermission resourceId binding that enforces per-record data scope. An authenticated user with the ordinary CLUE_MANAGEMENT_POOL:READ or CUSTOMER_MANAGEMENT_POOL:READ permission can supply another record's id and cause unscoped primary-key getters to return leads or accounts owned by other users, departments, or organizations. Exposed data includes contact names, phone numbers, owner and department attribution, and custom field values. This issue is fixed in version 1.7.4.

AnalysisAI

Broken object-level authorization (IDOR/BOLA) in CordysCRM allows any authenticated user holding the ordinary CLUE_MANAGEMENT_POOL:READ or CUSTOMER_MANAGEMENT_POOL:READ permission to read leads and customer accounts belonging to other users, departments, or organizations by supplying an arbitrary record ID to GET /pool/lead/get/{id} or GET /pool/account/get/{id}. The flaw affects all CordysCRM deployments prior to version 1.7.4 and is read-only in effect, but it exposes highly sensitive CRM data including contact names, phone numbers, owner and department attribution, and custom field values, with no special privileges, administrative rights, or non-default configuration required beyond valid credentials. …

Vulnerability AssessmentAI

Exploitation Requires an authenticated CordysCRM account (pre-1.7.4) holding the ordinary CLUE_MANAGEMENT_POOL:READ or CUSTOMER_MANAGEMENT_POOL:READ permission. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a broken-object-level-authorization (IDOR/BOLA, CWE-639) information-disclosure flaw, not a critical RCE. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Vendor-released patch: upgrade to CordysCRM 1.7.4, which resolves the missing per-record scope binding by adding pool-membership/organization validation (checkPoolMember with SessionUtils.getUserId() and OrganizationContext.getOrganizationId()) ahead of the vulnerable getters and other pool endpoints - see https://github.com/1Panel-dev/CordysCRM/releases/tag/v1.7.4, advisory GHSA-hxp2-5w5p-2grq, PR https://github.com/1Panel-dev/CordysCRM/pull/2976, and commit 34c7c3e5de2585208744926007530037a4ce4da5. … Detailed patch versions, workarounds, and compensating controls in full report.
