CVE-2025-71389 (GCVE-0-2025-71389)

Vulnerability from nvd – Published: 2026-07-23 21:16 – Updated: 2026-07-24 22:07

Title

Cal.com before 5.9.9 Remote Code Execution via RSC

Summary

Cal.com (calcom/cal.diy) before 5.9.9 is vulnerable to unauthenticated remote code execution because it bundles a version of Next.js whose React Server Components (RSC) request handling deserializes attacker-controlled input. A remote attacker can send a crafted RSC request to the server and cause arbitrary code to be executed during server-side processing, without authentication or user interaction. The flaw derives from the upstream Next.js vulnerability CVE-2025-55182 and is resolved in 5.9.9 by updating the affected dependency.

CVE-2024-58355 (GCVE-0-2024-58355)

Vulnerability from nvd – Published: 2026-07-23 21:16 – Updated: 2026-07-24 21:35

Title

Cal.com through 4.7.15 Cross-Site Scripting via booking questions

Summary

Cal.com (calcom/cal.diy) versions through 4.7.15 contain a stored cross-site scripting vulnerability. The single booking view (e.g., https://app.cal.com/booking/<id>) renders booking-question field labels via React's dangerouslySetInnerHTML without sanitizing or escaping user input. An attacker who can create an event type with a malicious booking-question label can inject arbitrary HTML/JavaScript that executes when a victim opens the crafted booking URL. The issue is fixed in v4.7.16.

Title

cal.com Repository Takeover via pull_request_target Workflow

Summary

cal.com (calcom repository, later renamed cal.diy) is affected by a repository takeover vulnerability in its GitHub Actions workflows. The workflow pr.yml uses the pull_request_target trigger with the repository's default write permissions and passes them down to check-types.yml. check-types.yml then performs a 'dangerous' checkout of the attacker-submitted pull request code (via the dangerous-git-checkout action) and subsequently executes it (through yarn install and package.json scripts). An attacker can open a pull request whose code runs arbitrary commands with the repository's write-scoped GITHUB_TOKEN, allowing them to push commits, merge or mutate pull requests, add or delete comments, and delete or force-push branches, thereby compromising the repository. The main branch is affected; no patched version is available.

Title

Cal.com through 4.7.15 Cross-Site Scripting via booking questions

Summary

Cal.com (repository calcom/cal.diy) in versions <= 4.7.15 is vulnerable to cross-site scripting (XSS) on the publicly accessible single booking view (e.g., /booking/<id>). Booking question (form field) labels are rendered via React's dangerouslySetInnerHTML without proper input sanitization or CSP, so an attacker who can create an event type with a malicious booking question label can inject arbitrary HTML/JavaScript that executes when a victim visits the booking view URL. Self-hosted instances with open registration are particularly at risk. The issue is fixed in version 4.7.16.

CVE-2025-71389 (GCVE-0-2025-71389)

Vulnerability from cvelistv5 – Published: 2026-07-23 21:16 – Updated: 2026-07-24 22:07

Title

Cal.com before 5.9.9 Remote Code Execution via RSC

Summary

Cal.com (calcom/cal.diy) before 5.9.9 is vulnerable to unauthenticated remote code execution because it bundles a version of Next.js whose React Server Components (RSC) request handling deserializes attacker-controlled input. A remote attacker can send a crafted RSC request to the server and cause arbitrary code to be executed during server-side processing, without authentication or user interaction. The flaw derives from the upstream Next.js vulnerability CVE-2025-55182 and is resolved in 5.9.9 by updating the affected dependency.

CVE-2024-58355 (GCVE-0-2024-58355)

Vulnerability from cvelistv5 – Published: 2026-07-23 21:16 – Updated: 2026-07-24 21:35

Title

Cal.com through 4.7.15 Cross-Site Scripting via booking questions

Summary

Cal.com (calcom/cal.diy) versions through 4.7.15 contain a stored cross-site scripting vulnerability. The single booking view (e.g., https://app.cal.com/booking/<id>) renders booking-question field labels via React's dangerouslySetInnerHTML without sanitizing or escaping user input. An attacker who can create an event type with a malicious booking-question label can inject arbitrary HTML/JavaScript that executes when a victim opens the crafted booking URL. The issue is fixed in v4.7.16.

CVE-2024-58354 (GCVE-0-2024-58354)

Vulnerability from cvelistv5 – Published: 2026-07-23 21:16 – Updated: 2026-07-24 21:35

Title

cal.com Repository Takeover via pull_request_target Workflow

Summary

cal.com (calcom repository, later renamed cal.diy) is affected by a repository takeover vulnerability in its GitHub Actions workflows. The workflow pr.yml uses the pull_request_target trigger with the repository's default write permissions and passes them down to check-types.yml. check-types.yml then performs a 'dangerous' checkout of the attacker-submitted pull request code (via the dangerous-git-checkout action) and subsequently executes it (through yarn install and package.json scripts). An attacker can open a pull request whose code runs arbitrary commands with the repository's write-scoped GITHUB_TOKEN, allowing them to push commits, merge or mutate pull requests, add or delete comments, and delete or force-push branches, thereby compromising the repository. The main branch is affected; no patched version is available.

CVE-2024-58353 (GCVE-0-2024-58353)

Vulnerability from cvelistv5 – Published: 2026-07-23 21:16 – Updated: 2026-07-24 21:35

Title

Cal.com through 4.7.15 Cross-Site Scripting via booking questions

Summary

Cal.com (repository calcom/cal.diy) in versions <= 4.7.15 is vulnerable to cross-site scripting (XSS) on the publicly accessible single booking view (e.g., /booking/<id>). Booking question (form field) labels are rendered via React's dangerouslySetInnerHTML without proper input sanitization or CSP, so an attacker who can create an event type with a malicious booking question label can inject arbitrary HTML/JavaScript that executes when a victim visits the booking view URL. Self-hosted instances with open registration are particularly at risk. The issue is fixed in version 4.7.16.

Booking question (form field) labels are rendered via React\u0027s dangerouslySetInnerHTML without proper input sanitization or CSP, so an attacker who can create an event type with a malicious booking question label can inject arbitrary HTML/JavaScript that executes when a victim visits the booking view URL. Self-hosted instances with open registration are particularly at risk. The issue is fixed in version 4.7.16."

Title

cal.diy 6.2.0 Conferencing OAuth Callback Open Redirect via Unsigned State

Summary

cal.diy through 6.2.0 contains an open redirect vulnerability in the conferencing OAuth callback endpoint that allows attackers to redirect users to arbitrary URLs by crafting malicious state parameters. Attackers can exploit the unsigned state parameter and onErrorReturnTo field to silently redirect visitors from the trusted domain to attacker-controlled URLs for phishing attacks.
