Vulnerability from nvd – Published: 2026-08-17 11:04 – Updated: 2026-08-17 16:04

Title

stoatchat before 0.15.0 Missing Authorization via Subscribe

Summary

stoatchat before 0.15.0 contains a missing authorization vulnerability in the Subscribe message handler that allows authenticated attackers to enumerate members and monitor profile updates of private servers without membership. Attackers can subscribe to any server's member-update topic by sending a Subscribe message with an arbitrary server ID, receiving live UserUpdate events including display names, avatars, and status changes for members they should not have access to.

CVE-2026-73059 (GCVE-0-2026-73059)

Vulnerability from nvd – Published: 2026-08-16 13:14 – Updated: 2026-08-17 16:05

Title

stoatchat before 0.15.0 Permission Bypass via message_fetch

Summary

stoatchat before 0.15.0 contains a permission bypass vulnerability in the message_fetch route that checks only ViewChannel permission instead of requiring ReadMessageHistory. Attackers with ViewChannel access but ReadMessageHistory denied can retrieve individual message content by ID, bypassing the intended history restriction enforced by bulk read routes.

CVE-2026-73058 (GCVE-0-2026-73058)

Vulnerability from nvd – Published: 2026-08-16 13:14 – Updated: 2026-08-17 16:56

Title

stoatchat before 0.15.0 SSRF via IPv6 unspecified address bypass

Summary

stoatchat versions before 0.15.0 fail to block the IPv6 unspecified address (::) in the SSRF blocklist, allowing unauthenticated attackers to bypass protections via the /proxy and /embed endpoints. Attackers can craft requests using IPv6 literal syntax to access services on the loopback interface and retrieve sensitive internal content.

CVE-2026-73057 (GCVE-0-2026-73057)

Vulnerability from nvd – Published: 2026-08-16 13:14 – Updated: 2026-08-18 14:05

Title

stoatchat before 0.15.0 Uncapped SVG Rendering Denial of Service

Summary

stoatchat before 0.15.0 fails to validate SVG viewBox dimensions in the proxy endpoint, allowing attackers to cause denial of service by memory exhaustion. Attackers can host malicious SVGs with extremely large width and height values and trigger concurrent requests to exhaust available memory across proxy replicas.

CVE-2026-57848 (GCVE-0-2026-57848)

Vulnerability from nvd – Published: 2026-07-18 19:15 – Updated: 2026-07-20 17:45

Title

Stoat for Android Internal File Disclosure via Exported ShareTargetActivity URI Validation

Summary

Stoat for Android exports the chat.stoat.activities.ShareTargetActivity component (reachable to any process on the device via the android.intent.action.SEND intent) and accepts the file to share as a URI supplied through the android.intent.extra.STREAM extra. The activity does not validate or filter the incoming URI before using it as the outgoing attachment, so a caller can pass a file:// URI pointing at the application's own internal storage (for example /data/data/chat.revolt/databases/revolt.db, cached authentication token files, or preferences) and have the app treat that internal file as a user-selected attachment. An attacker who can invoke intents on the victim's device (via ADB access, a co-installed malicious application, or any other route that reaches Android's intent dispatch) can launch ShareTargetActivity with such a URI and cause the victim, on a single channel-selection interaction, to send the internal file to any Stoat channel or user of the attacker's choosing. The composer displays the attachment as \"attachment\" with no filename indication, so the victim has no visible signal that the file being sent is their own internal application data. Consequences include disclosure of the local Stoat database (message history, contact list, cached content), disclosure of authentication tokens permitting full account takeover, and disclosure of any other file readable by the app process.

The activity does not validate or filter the incoming URI before using it as the outgoing attachment, so a caller can pass a file:// URI pointing at the application\u0027s own internal storage (for example /data/data/chat.revolt/databases/revolt.db, cached authentication token files, or preferences) and have the app treat that internal file as a user-selected attachment. An attacker who can invoke intents on the victim\u0027s device (via ADB access, a co-installed malicious application, or any other route that reaches Android\u0027s intent dispatch) can launch ShareTargetActivity with such a URI and cause the victim, on a single channel-selection interaction, to send the internal file to any Stoat channel or user of the attacker\u0027s choosing. The composer displays the attachment as \\\"attachment\\\" with no filename indication, so the victim has no visible signal that the file being sent is their own internal application data. Consequences include disclosure of the local Stoat database (message history, contact list, cached content), disclosure of authentication tokens permitting full account takeover, and disclosure of any other file readable by the app process."

CVE-2026-63088 (GCVE-0-2026-63088)

Vulnerability from nvd – Published: 2026-07-16 16:40 – Updated: 2026-07-16 18:00 X_Open Source

Title

stoatchat < 0.14.0 SSRF via DNS-based IP Blocklist Bypass

Summary

stoatchat before 0.14.0 contains a server-side request forgery (SSRF) vulnerability that allows unauthenticated network-accessible attackers to bypass the DNS-based IP blocklist by exploiting incomplete address validation in the url_is_blacklisted function, which inspects only the first resolved address while the underlying HTTP client iterates all cached addresses.

Severity

7.7 (High)

CVE-2025-71388 (GCVE-0-2025-71388)

Vulnerability from nvd – Published: 2026-07-16 12:19 – Updated: 2026-07-20 22:14

Title

stoatchat 20241213-1 Webhook Token Disclosure via Read Permissions

Summary

stoatchat (delta/Revolt) versions from 20241213-1 before 20250210-1 allow users with only ViewChannel (read) permission on a channel to fetch that channel's webhooks, including their tokens, because the webhook fetch endpoint checked for ViewChannel instead of ManageWebhooks. Using a retrieved token, an attacker can send arbitrary messages to the channel, bypassing channel permissions and impersonating a bot or webhook. Fixed in 20250210-1 (0.8.2).

Severity

7.6 (High)

CVE-2025-71377 (GCVE-0-2025-71377)

Vulnerability from nvd – Published: 2026-07-16 12:19 – Updated: 2026-07-20 22:14

Title

stoatchat before 20250210-1 Unrestricted Message History Fetch

Summary

stoatchat (delta) versions before 20250210-1 (0.8.2) contain a logic error in the query messages route. When fetching messages 'nearby' another message, the database query can be given a message limit of zero, which the database interprets as 'no limit'. A remote unauthenticated attacker can craft nearby message fetch requests to download an entire channel's message history in a single expensive request, and can send many such requests in parallel, resulting in denial of service through resource exhaustion.

Severity

8.7 (High)

CVE-2026-73059 (GCVE-0-2026-73059)

Vulnerability from cvelistv5 – Published: 2026-08-16 13:14 – Updated: 2026-08-17 16:05

Title

stoatchat before 0.15.0 Permission Bypass via message_fetch

Summary

stoatchat before 0.15.0 contains a permission bypass vulnerability in the message_fetch route that checks only ViewChannel permission instead of requiring ReadMessageHistory. Attackers with ViewChannel access but ReadMessageHistory denied can retrieve individual message content by ID, bypassing the intended history restriction enforced by bulk read routes.

Severity

7.1 (High)

CVE-2026-73058 (GCVE-0-2026-73058)

Vulnerability from cvelistv5 – Published: 2026-08-16 13:14 – Updated: 2026-08-17 16:56

Title

stoatchat before 0.15.0 SSRF via IPv6 unspecified address bypass

Summary

stoatchat versions before 0.15.0 fail to block the IPv6 unspecified address (::) in the SSRF blocklist, allowing unauthenticated attackers to bypass protections via the /proxy and /embed endpoints. Attackers can craft requests using IPv6 literal syntax to access services on the loopback interface and retrieve sensitive internal content.

CVE-2026-73057 (GCVE-0-2026-73057)

Vulnerability from cvelistv5 – Published: 2026-08-16 13:14 – Updated: 2026-08-18 14:05

Title

stoatchat before 0.15.0 Uncapped SVG Rendering Denial of Service

Summary

stoatchat before 0.15.0 fails to validate SVG viewBox dimensions in the proxy endpoint, allowing attackers to cause denial of service by memory exhaustion. Attackers can host malicious SVGs with extremely large width and height values and trigger concurrent requests to exhaust available memory across proxy replicas.

CVE-2026-57848 (GCVE-0-2026-57848)

Vulnerability from cvelistv5 – Published: 2026-07-18 19:15 – Updated: 2026-07-20 17:45

Title

Stoat for Android Internal File Disclosure via Exported ShareTargetActivity URI Validation

Summary

Stoat for Android exports the chat.stoat.activities.ShareTargetActivity component (reachable to any process on the device via the android.intent.action.SEND intent) and accepts the file to share as a URI supplied through the android.intent.extra.STREAM extra. The activity does not validate or filter the incoming URI before using it as the outgoing attachment, so a caller can pass a file:// URI pointing at the application's own internal storage (for example /data/data/chat.revolt/databases/revolt.db, cached authentication token files, or preferences) and have the app treat that internal file as a user-selected attachment. An attacker who can invoke intents on the victim's device (via ADB access, a co-installed malicious application, or any other route that reaches Android's intent dispatch) can launch ShareTargetActivity with such a URI and cause the victim, on a single channel-selection interaction, to send the internal file to any Stoat channel or user of the attacker's choosing. The composer displays the attachment as \"attachment\" with no filename indication, so the victim has no visible signal that the file being sent is their own internal application data. Consequences include disclosure of the local Stoat database (message history, contact list, cached content), disclosure of authentication tokens permitting full account takeover, and disclosure of any other file readable by the app process.

CVE-2026-63088 (GCVE-0-2026-63088)

Vulnerability from cvelistv5 – Published: 2026-07-16 16:40 – Updated: 2026-07-16 18:00 X_Open Source

Title

stoatchat < 0.14.0 SSRF via DNS-based IP Blocklist Bypass

Summary

stoatchat before 0.14.0 contains a server-side request forgery (SSRF) vulnerability that allows unauthenticated network-accessible attackers to bypass the DNS-based IP blocklist by exploiting incomplete address validation in the url_is_blacklisted function, which inspects only the first resolved address while the underlying HTTP client iterates all cached addresses.

Severity

7.7 (High)

CVE-2025-71388 (GCVE-0-2025-71388)

Vulnerability from cvelistv5 – Published: 2026-07-16 12:19 – Updated: 2026-07-20 22:14

Title

stoatchat 20241213-1 Webhook Token Disclosure via Read Permissions

Summary

stoatchat (delta/Revolt) versions from 20241213-1 before 20250210-1 allow users with only ViewChannel (read) permission on a channel to fetch that channel's webhooks, including their tokens, because the webhook fetch endpoint checked for ViewChannel instead of ManageWebhooks. Using a retrieved token, an attacker can send arbitrary messages to the channel, bypassing channel permissions and impersonating a bot or webhook. Fixed in 20250210-1 (0.8.2).

Severity

7.6 (High)

CVE-2025-71377 (GCVE-0-2025-71377)

Vulnerability from cvelistv5 – Published: 2026-07-16 12:19 – Updated: 2026-07-20 22:14

Title

stoatchat before 20250210-1 Unrestricted Message History Fetch

Summary

stoatchat (delta) versions before 20250210-1 (0.8.2) contain a logic error in the query messages route. When fetching messages 'nearby' another message, the database query can be given a message limit of zero, which the database interprets as 'no limit'. A remote unauthenticated attacker can craft nearby message fetch requests to download an entire channel's message history in a single expensive request, and can send many such requests in parallel, resulting in denial of service through resource exhaustion.

Severity

8.7 (High)
