CVE ID :CVE-2026-17183 Published : Aug. 19, 2026, 5:30 p.m. | 19 minutes ago Description :Summary An authenticated organization user who can create or edit alert rules in a folder can query a datasource for which they do not have datasources:query permission. The attacker sets the client-controlled query field queryType to __expr__ while retaining the UID of a real datasource. The alert-rule authorization path treats the query as a server-side expression and skips datasource permission enforcement, while the evaluator subsequently resolves and executes the query against the real datasource identified by datasourceUid. ## Impact This bypass can expose data accessible through Grafana's configured datasource credentials to a low-privileged user who is not authorized to query that datasource directly. Confidentiality impact is High. Integrity impact is Low because some datasource backends and configured credentials may permit state-changing queries. No availability impact has been demonstrated. ## Attack prerequisites - Authenticated, low-privileged user in the same Grafana organization - Permission to create or edit alert rules in an accessible folder - No datasources:query permission for the targeted datasource - Knowledge or discovery of the targeted datasource UID - No user interaction required ## Technical details / root cause 1. The attacker submits an alert-rule query with queryType: "__expr__" and the UID of a real datasource. 2. The datasource authorization helper skips permission enforcement when query.QueryType == "__expr__". 3. queryType is client-controlled and is not validated against the referenced datasource. 4. During evaluation, Grafana selects and loads the actual datasource using DatasourceUID, not the spoofed queryType. 5. The query therefore executes using Grafana's datasource credentials despite the caller lacking datasources:query. The root cause is inconsistent query classification between authorization and execution: authorization trusts que...

CVE ID :CVE-2026-71866 Published : Aug. 19, 2026, 5:27 p.m. | 22 minutes ago Description :Orval generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications. From version 8.19.0 until 8.21.0, a double quote in a schema property name is emitted into the generated zod.object({...}) schema without safe encoding. This permits attacker-controlled JavaScript to be evaluated when the generated zod schema module is imported, resulting in code execution in the developer, CI, test, or application environment. The affected code is packages/zod/src/index.ts and zod object-key generation. This issue is fixed in version 8.21.0.

FFmpeg before commit 983dae9 contains an out-of-bounds read in the AV1 RTP packetizer (libavformat/rtpenc_av1.c). The keyframe detection loop that searches for a sequence header OBU advanced its pointer and remaining-size counter by the encoded header length plus the OBU payload size without first bounding the OBU size against the remaining data. A crafted OBU size causes the remaining-size counter to wrap to a positive value, causing the next loop iteration to dereference a pointer beyond the end of the packet buffer. A crafted AV1 input packet muxed to RTP triggers the out-of-bounds read.

FFmpeg before commit 65b0dab contains an out-of-bounds read in the DASH demuxer (libavformat/dashdec.c). When a live DASH manifest is refreshed with a startNumber that is lower than the previous value, the current sequence number is driven negative. The fragment retrieval function checked only the upper bound before indexing the fragments array, allowing a negative index to be used and causing an out-of-bounds read. A malicious or misconfigured DASH server can trigger this by serving a live manifest with a decreasing startNumber across a manifest refresh.

CVE ID :CVE-2026-75583 Published : Aug. 19, 2026, 5:21 p.m. | 28 minutes ago Description :keeper.sh's calendar module version prior to 2.18.14 contains a server-side request forgery (SSRF) guard bypass vulnerability that allows authenticated attackers to reach private network addresses by exploiting a DNS rebinding attack against the two-phase URL validation and connection flow. The SSRF guard validates a hostname's resolved IP addresses but discards them before the actual HTTP connection is opened, allowing an attacker who controls authoritative DNS to return a public address during validation and a private address during the subsequent independent socket-level DNS resolution, causing the guard to pass while the outbound connection reaches internal infrastructure such as cloud instance metadata endpoints.

FFmpeg before commit 1cdeb3c contains a heap buffer overflow vulnerability in the VC-2/Dirac RTP packetizer (libavformat/rtpenc_vc2hq.c) that allows attackers to trigger memory corruption by supplying a crafted Dirac data unit. The packetizer copies an input-derived data unit or fragment size into a fixed-size buffer without an upper bound check, causing a heap buffer overflow when the crafted input is packetized for RTP output.

FFmpeg before commit 1c10bcc contains a heap buffer overflow in the RIST protocol reader (libavformat/librist.c). librist_read() ignored its size argument and copied the full received payload length into the caller-provided destination buffer, overflowing it when the payload exceeds the destination size. This is reachable via the async:rist:// URL scheme, where the async wrapper supplies a smaller buffer than the received payload. A remote RIST sender can trigger the overflow by sending a packet whose payload exceeds the caller buffer size.

FFmpeg before commit 9d786e4 contains a stack buffer overflow in the MPEG-PS muxer (libavformat/mpegenc.c). When muxing input with more streams than the muxer's fixed-size stack buffer accommodates, the buffer is overflowed. A crafted input with an excessive number of streams triggers the overflow during MPEG-PS muxing.

FFmpeg before commit acf5d7c contains a heap buffer overflow in the hvcC box writer. When writing an HEVC configuration record with more NAL units of a single type than the count field can represent, the NAL unit count overflows, causing a heap buffer overflow. A crafted HEVC input file triggers the overflow during muxing.

CVE ID :CVE-2026-75145 Published : Aug. 19, 2026, 5:21 p.m. | 28 minutes ago Description :FFmpeg before commit b4c199c contains an incorrect integer narrowing conversion in the AV1 RTP packetizer (libavformat/rtpenc_av1.c). The OBU size is cast to long before comparison against the remaining frame size. On targets where long is 32 bits, including 64-bit Windows, sufficiently large OBU size values are sign-flipped by the narrowing cast, producing a negative value that passes the payload size check. This allows an oversized OBU to bypass the safety bound on affected platforms, leading to out-of-bounds memory access when the oversized value is subsequently used as a copy length.
