CVE-2026-126305

EspoCRM before 10.0.9 Stored XSS via Knowledge Base Article Attachments

EspoCRM before 9.3.11 and 10.x before 10.0.9 contains a stored cross-site scripting vulnerability in Knowledge Base articles that lets users with Knowledge Base create or edit access attach a JavaScript file and add a crafted link to the article body. When an administrator clicks the link, the script runs in their session and can create an administrator account with attacker-chosen credentials.

EspoCRM before 10.0.8 Stored XSS via Malicious SVG Attachment

EspoCRM before 9.3.11 and 10.x before 10.0.8 contains a stored cross-site scripting vulnerability that allows low-privileged users to upload crafted SVG images that submit authenticated POST requests to arbitrary backend endpoints. Attackers can trick an administrator into opening the SVG in a separate browser tab and clicking it, performing administrator actions such as elevating the attacker's account to administrator.

EspoCRM before 9.3.11 and 10.0.8 Unauthenticated Denial of Service via Password-Redaction Regex

EspoCRM before 9.3.11 and 10.x before 10.0.8 contains a denial of service vulnerability in which the password-redaction regular expression applied during API error handling consumes excessive CPU on long request bodies. Unauthenticated remote attackers can concurrently send a small number of large API requests to exhaust server workers, making EspoCRM slow or unavailable to legitimate users.

CVE-2026-53574

EspoCRM: Blind SQL injection via streamAttachments where-clause complex expression

EspoCRM is an open source customer relationship management application. From 8.1.0 until 9.3.8, an authenticated non-administrator can submit a crafted where parameter to the GET entity streamAttachments endpoint because that query path permits complex expressions. Boolean-based blind SQL injection can extract arbitrary database information, including active administrator session tokens, and can enable full privilege escalation. This issue is fixed in version 9.3.8.

EspoCRM: Persistent XSS via CSP nonce injection in applicationName setting by admin user

EspoCRM is an open source customer relationship management application. Prior to 9.3.9, an authenticated administrator can place crafted content in the applicationName setting through CSP nonce injection. The persistent injection is inserted into the main application page without escaping, allowing attacker-controlled JavaScript to run in users' sessions and leak page data, including unsaved user input. This issue is fixed in version 9.3.9.

EspoCRM: Mass email template renderer leaks restricted record fields

EspoCRM is an open source customer relationship management application. Prior to 10.0.3, a user with email-template edit access and mass-email sending access can reference restricted record fields in a template because the renderer stops filtering those fields when per-user ACL application is disabled. The same behavior affects group email auto-replies when a regular user can edit the selected template, even though an administrator controls the group email. Rendered messages can disclose restricted user fields. This issue is fixed in version 10.0.3.

EspoCRM: Pre-authentication stored HTML injection in stream notification emails about email received

EspoCRM is an open source customer relationship management application. Prior to 9.3.9, an unauthenticated remote attacker can send an email to a monitored group or IMAP address, including an email-to-Case address, and place arbitrary HTML in its plain-text body. EspoCRM stores that body and renders it without escaping in Email Received stream notification emails sent to users following the related record, allowing HTML injection and, in mail clients that execute it, JavaScript execution. Earlier sanitization for Post and Mention notifications did not cover this notification path. This issue is fixed in version 9.3.9.

EspoCRM is an open source customer relationship management application. Prior to 9.3.7, an authenticated administrator can supply crafted serialized PHP object data that is stored in background MassAction or Export parameters and later deserialized by the application. The deserialization paths do not restrict allowed classes, allowing attacker-controlled object instantiation and arbitrary code execution on the server. This issue is fixed in version 9.3.7.

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.

EspoCRM is an open source customer relationship management application. Prior to 9.3.10, an authenticated administrator can provide crafted input to the administrative Label Manager. Insufficient path validation allows traversal outside the intended directory and permits reading, modifying, creating, or deleting JSON files accessible to the application, subject to filesystem permissions and server configuration. This issue is fixed in version 9.3.10.

EspoCRM: CSV/Formula Injection sanitizer bypass via leading whitespace/control characters in export

EspoCRM is an open source customer relationship management application. Prior to 9.3.9, application/Espo/Tools/Export/Format/Csv/Processor.php, application/Espo/Tools/Export/Format/Xlsx/OpenSpoutProcessor.php, and application/Espo/Tools/Export/Format/Xlsx/PhpSpreadsheetProcessor.php inspect only the first byte in sanitizeCellValue(). An authenticated low-privileged user can store a free-text value whose formula trigger is preceded by whitespace or a control character, causing CSV or XLSX export to omit the leading single-quote formula-neutralization prefix. When a privileged user opens the exported file and accepts applicable spreadsheet security prompts, spreadsheet software can ignore the whitespace or control-character prefix and evaluate the cell as a formula, permitting outbound data disclosure and, on legacy configurations with DDE enabled, command execution. This issue is fixed in version 9.3.9.

EspoCRM: Portal User ACL Bypass Exposes Internal Stream Notes

EspoCRM is an open source customer relationship management application. Prior to 9.3.7, a portal user with stream access to a parent record can directly fetch a Note through the portal Note API and read an internal stream note when the note identifier is known. Stream list responses correctly hide notes whose isInternal field is true, but the direct single-Note access check does not enforce that restriction, exposing internal agent content. This issue is fixed in version 9.3.7.
